Sorption of Noble Metals on Silica Gel Chemically Modified with -(5-Mercapto-1,3,4-Thiadiazol-2-yl)-'-Propylurea Groups

Sorption processes of noble metals on silica gel surface with covalently grafted N- (5-mercapto-1,3,4-thiadiazol-2-yl)- N '-propylurea groups (MTS) were studied. It was found that sorption onto MTS may occur via complexation and/or anion-exchange mechanisms depending on the acidity of the solut...
