Abstract

The article studies the thermal stability and surface morphology of the immobilized ligand obtained on the basis of in situ covalent attachment of O, O-di- (2-aminoethyl) -dithiophosphate potassium on a urea-formaldehyde matrix. As a result of the conducted thermal studies, it was determined that the resulting ligand is stable up to 128 ° C, and also has a high sorption capacity for non-ferrous metals due to its microporous surface structure.
