Hasebe, Shigeru published the artcileRemoval of lead(2+) ion by absorbing particle flotation using zeolite, Name: Dodecylamineacetate, the publication is Iwate Daigaku Kogakubu Kenkyu Hokoku (1983), 53-9, database is CAplus.
The flotation of zeolite with dodecylamine?acetate (DAA) [2016-56-0] for the removal of Pb2+ was investigated. Zeolite particle can be effectively floated with DAA at pH 2-7. The suitable size of zeolite for flotation with a column type separator is 104-137¦Ì, and the recovery of zeolite is ?95% with DAA 15 kg/ton. Under the same conditions, the column flotation showed a higher recovery of zeolite and removal of Pb2+ than did the Denver type flotation equipment. The zeolite may be used for 3 cycles to remove Pb2+. Adsorbing particle flotation in the column can be treated with a higher concentration and for a shorter time than with the percolation method.
