ELECTRON MICROSCOPIC INVESTIGATION OF ION-EXCHANGE MATERIALS SYNTHESIZED BASED ON DIMETHYLOL CARBAMIDE, DIMETHYLOL THIOCARBAMIDE, AND DIGLYCIDYL THIOCARBAMATE

In many studies, the scanning electron microscopy (SEM) method is widely used to determine the morphological and surface structure of various adsorbent materials [104; 204–208]. This is because the morphological structure of sorbents significantly influences their physicochemical properties.
