SYNTHESIS OF COMPLEX-GENERATING SORBENT BASED ON DIETHYLDITHIOCARBAMATE
Keywords:
sorbent, urea, formaldehyde, diethyldithiocarbamic acid, IR-spectrum.Abstract
In this article, the optimal conditions for the synthesis of a complex-forming sorbent based on urea, formaldehyde and diethyldithiocarbamic acid have been determined. In this case, the initial substances were taken in the ratio of 1:1:2.5 mol, the temperature was 40oC and 80-95oC and the environment (pH=8-10) was carried out, and as a result, the yield of the reaction was 90%. Properties such as moisture content of this obtained sorbent, bulk density, static exchange capacity of sorbent and density of sorbent in hydrated state were determined. IR-spectroscopic analysis of the obtained sorbent and the complex formed by it with metal was studied.
