Sorption of transition metals by silica gel with fixed amide of maleic acid and polyhexamethyleneguanidine on the surface

New Approach to Synthesis of Silica with Chemically Bound Guanidine Hydrochloride for Preconcentration of Metal Ions

“…Immobilization of compounds with amphiphilic properties has attracted considerable interest. In our previous studies [8]- [10] it was shown that silicas chemically modified with polyhexamethyleneguanidine and its carboxyl-containing…”
