Shamsipur, Mojtaba published the artcileThe synthesis of 1,4-diaza-2,3;8,9-dibenzo-7,10-dioxacyclododecane-5,12-dione and its use in calcium-selective carbon paste electrodes, Category: catalysis-chemistry, the publication is Journal of Inclusion Phenomena and Macrocyclic Chemistry (2001), 40(4), 303-307, database is CAplus.
A synthetic procedure was developed for the preparation of 1,4-diaza-2,3;8,9-dibenzo-7,10-dioxacyclododecane-5,12-dione. A C paste electrode based on the new macrocyclic diamide was constructed for Ca2+ determination The calibration graph was linear over a wide concentration range (1.3 ¡Á 10-6-3.2 ¡Á 10-3 M) with a near Nernstian slope of 32 mV decade-1. The limit of detection is 7.9 ¡Á 10-7 M (0.032 ppm). Selectivity coefficients were tabulated and the working pH range was determined It has a fast response time of <10 s and can be used for at least 3 mo without any considerable divergence in potentials. The electrode was successfully applied to the determination of Ca2+ ions in a pharmaceutical preparation
