CHEMISTRY AND CHEMICAL ENGINEERING
The sorption and complex-forming properties of PAD600-based impregnated sorbents with respect to the Pt (II) ion were studied. The parameters of sorption extraction of platinum ions are determined. It was found that impregnated sorbents have the best sorption properties with respect to platinum cations. Based on the processing of the integral kinetic sorption curves, it has been established that the sorption process proceeds according to second-order models. The use of chemical kinetics models has shown that the stage of chemical interaction of platinum (II) ions with functional groups of the sorbent also contributes to the overall process rate.

CHEMISTRY AND CHEMICAL ENGINEERING
The aim of this work is the synthesis, study of the crystal and molecular structure of coordination compounds of cadmium with 2-amino-1-methylbenzimidazole. For the first time, the crystal structures of mixed ligand complexes of 2-amino-1-methylbenzimidazole (L) with various acidoligands (acetate and nitrate) with the distorted-octahedral structure of the metal polyhedron - [CdL2 (Ac)2] H2O and [CdL2 (NO3)2 (Н2О)2] were determined. The ligand molecule is coordinated through the nitrogen atom of the heterocyclic ring, the acidoligand is monodentate coordinated in the crystal structure of the complex. The presence of hydrated or innersphere water molecules in the molecules leads to the formation …
