Chao, Chen Shen published the artcileAdsorption study. III. Adsorption of surfactants on the acrylic glass surface, Computed Properties of 2016-56-0, the publication is Yingyong Jiemian Huaxue (1982), 7-12, database is CAplus.

Eleven typical anionic, cationic, and nonionic surfactants were used to study their adsorption on the acrylic glass surface. With the exception of dodecyl ammonium acetate, all of the other surfactants were adsorbed with their nonpolar groups and with their polar groups exposed. The concentration necessary for saturated adsorption and the hydrophilicity (from contact angle measurement of water drop) were closely related to the structures of the surfactants. For anionic and cationic surfactants with smaller and more polar groups, the concentration for saturated adsorption is lower than those with larger and less polar groups. The P.O.E. ether phosphate has a very high hydrophilicity (very small contact angle) due to the high polarizability of its polar group. The concentration for saturated adsorption of P.O.E. (polyoxyethylene) type nonionic surfactants is very high due to the steric effect of the bulky P.O.E. group.

Yamashita, Hiroshi published the artcileIon flotation of metal-(1-hydroxyethylidene)bisphosphonate complexes and determination of stability constants of the complexes, Name: Dodecylamineacetate, the publication is Nippon Kagaku Kaishi (1991), 168-9, database is CAplus.

Ion flotation of sixteen metal ions (Mn(II), Co(II), Cd(II), Zn(II), Ni(II), Cu(II), Pb(II), Bi(III), Fe(III), In(III), Ga(III), Cr(III), Y(III), V(V), Mo(VI), Cr(VI)) was investigated in (1-hydroxyethylidene)bisphosphonic acid (HEBP) solutions with dodecylammonium acetate (DAA) as a surfactant. A 20 cm³ aliquot of 4.38 ¡Á 10^-4 mol.dm^-3 HEBP solution containing (3.94?4.32) ¡Á 10^-4 mol/dm³ of the above-mentioned metal ions and 8.77 ¡Á 10^-4 mol/dm³ of DAA was adjusted to the desired pH and subjected to flotation in a cell (20 ¡Á 2.5 cm i.d.) for 10 ? 20 min with nitrogen bubbles. The effect of pH on the recovery of metal ions was examined and recoveries of 98?100% (except for Cr(VI)) were obtained at the appropriate pH ranges. The compositions of the floated complexes were determined to be a metal/HEBP ratio of 1:1 for the divalent metal ions. The stability constants of the complexes were also determined from the pH?percent flotation curves by nonlinear least-squares method.

Nozaki, Toru published the artcileComplex formation of (1-hydroxyethylidene)bisphosphonic acid and flotation with the complexes, Application of Dodecylamineacetate, the publication is Nippon Kagaku Kaishi (1989), 697-701, database is CAplus.

From the polarog. behavior of Cu(II), Pb(II), Cd(II), and Mn(II) ions in (1-hydroxyethylidene)bisphosphonic acid (HEBP, H₅L) solutions at an ionic strength of 0.4 mol/dm³ adjusted with sodium perchlorate, the compositions of the metal complexes and their stability constants were determined The species of MH₃L, MH₂L^–, MHL^2-, M(H₃L)₂^2-, M(H₃L)H₂L^3-, M(H₂L)₂^4-, and M(H₂L)HL^5- for Cu and Mn, and same species except MH₂L^– and MHL^2- for Cd, were found at pH 4.6-6.4. Species of MHL^2-, ML^3-, M(OH)L^4-, M(HL)₂^6-, and ML₂^8- were found in the pH ranges 11.5-12.9 for Pb(II). The flotation of HEBP by complexing with Fe(III) and the HEBP complexes was investigated. Recoveries of 4.0 ¡Á 10^-4 mol/dm³ of HEBP and the HEBP complexes of Cu(II), Pb(II) and Mn(II) were 99.6%, and 99.6, 98.6 and 91.5%, resp., by the flotation for about 5 min using (1.2 ? 1.6) ¡Á 10^-3 mol/dm³ of dodecylammonium acetate (DAA) as a surfactant at pH 6.0-9.5. The presence of 6382 ppm of Cl^–, 3840 ppm of SO₄^2- and 3100 ppm of NO₃^– did not interfere the flotation. Flotation of HEBP and the complexes proceeds through the formation of ion pair Rn_?MHi_?L, where n? = 5-n-i?, R and n denoting the cation of DAA and the charge of the metal, resp.

Itoh, Shinichi published the artcileFloatability of minerals from the tailings of tin ore dressing, Category: catalysis-chemistry, the publication is Tohoku Kogyo Gijutsu Shikensho Hokoku (1983), 21-6, database is CAplus.

Tantalite??[12178-48-2] is separated from cassiterite??[1317-45-9] by flotation with dodecylamine?acetate??[2016-56-0] because fine grinding is necessary to liberate the minerals and electrostatic separation is difficult to apply. The most important factor in the flotation is the electrochem. property of the solid-liquid interface, and the zeta-potential pH was determined as follows: tantalite 3.5, ilmenite??[12168-52-4], tourmaline, zircon, cassiterite 5.0, monazite??[1306-41-8], xenotime 6.0. Tantalite can be separated from monoazite at low pH because of the difference in zeta-potential, and adsorption of SO₄^2- on the tantalite surface.

Nakazawa, Hiroshi published the artcileSeparation of sericite from quartz by amine flotation, Recommanded Product: Dodecylamineacetate, the publication is Nippon Kogyo Kaishi (1988), 104(1209), 803-7, database is CAplus.

Sericite separation from quartz by flotation was investigated, using dodlecylammonium acetate (DAA) as the collector. Sericite floats in acidic solution with a large amount of DAA. Sericite can be selectively separated from quartz in a pH 2.5 solution The addition of Al³⁺ decreases the amount of DAA required for the flotation of sericite. In a pH 10.5 solution, the separation of sericite from quartz is not good but, with an addition of Al³⁺, sericite can be separated from quartz.

The utility of Bacillus polymyxa, a heterotrophic bacterium indigenous to ore deposits in the degradation of several flotation collectors was studied. Dodecyl amine, diamine, iso-Pr xanthate and Na oleate could be efficiently removed from alk. solutions through bioremediation in an environmentally acceptable fashion. The bacterial cells were capable of stripping adsorbed collector reagents from various mineral surfaces. Mechanisms of such a biodegradation process are illustrated through results from zeta potential, adsorption, bacterial growth and surface anal. studies.

Deo, Namita published the artcileBiodegradation of some organic reagents from mineral process effluents, HPLC of Formula: 2016-56-0, the publication is Process Metallurgy (1999), 687-696, database is CAplus.

Bacillus polymyxa were studied for the removal of organics such as dodecylamine, ether diamine, iso-Pr xanthate and Na oleate from wastewater. Time-bound removal of these organics from an alk. solution was studied under different exptl. conditions during bacterial growth and in the presence of metabolites by frequent monitoring of residual concentrations as a function of time, reagent concentration and cell d. The stages and mechanisms in the biodegradation process were monitored through UV-visible and FTIR spectroscopy. Surface chem. of the bacterial cells as well as the biosorption tendency for various organics were established through electrokinetic and adsorption d. measurements. Cationic amines were biosorbed followed by their degradation through bacterial metabolism The presence of the organics promoted bacterial growth through effective bacterial utilization of N and C from the organics Under optimal conditions, complete degradation and bioremoval of all the organics could be achieved.

Hu, B. published the artcileA study on the separation of fine cassiterite and quartz by liquid-liquid extraction, Application In Synthesis of 2016-56-0, the publication is Publications of the Australasian Institute of Mining and Metallurgy (1993), 3/93(XVIII International Mineral Processing Congress), 727-33, database is CAplus.

Fine cassiterite and quartz were separated by liquid-liquid extraction using iso-octane as an oil phase, dodecylamine acetate (DAA) as a collector, and sodium chloride as a depressant. With regard to the distribution of fine cassiterite and quartz between oil and aqueous phases, the effect of DAA was investigated in terms of pH, DAA and NaCl concentrations, zeta potential, and adsorption d. A maximum recovery of cassiterite in the oil phase was obtained with pH around 6.0, DAA concentration of 1.0 ¡Á 10^-5 mol/L, and NaCl addition of 0.1 mol/L. In these conditions of liquid-liquid extraction, most of the fine quartz remained in the aqueous phase. Thus NaCl was an effective depressant for fine quartz under optimum conditions. A series of separation tests by liquid-liquid extraction was then conducted for the mixed samples (6.0% Sn) of cassiterite and quartz. By a single separating process, the recovery of cassiterite in the oil phase was about 92% with a grade of 27% Sn. The same results could also be obtained by using kerosine in place of iso-octane as the oil phase.
