STUDY OF THE DEGREE OF SORPTION OF SORBENTS IN Pb(NO3)2 SOLUTION

The article presents the kinetics of sorption of lead ions in a solution of lead nitrate with composite polymer sorbents. A composite polymer sorbent is obtained from electrolyte polymers, which polymers consist of polyaniline and polyacrylic acid, as well as polyaniline and polycaproamide. The content of lead ions in a solution of lead nitrate is 45 mg∙ekv/l. Sorption kinetics was carried out in a temperature range from 20 to 50°C. In addition, the kinetics of sorption of composite polymer sorbents using bentonite and kaolin fillers was studied
