Search for effective modifiers by grafting on an inorganic surface

The process of inoculation of humic acids and their functional derivatives (chloro - and aminochloro-derivatives) on modified surfaces of burnt rock is studied. The search for a method of grafting humic compounds on carriers was carried out. Acidic and sorption properties of grafted surfaces of humic sorbents with respect to heavy metal ions are characterized. It was found that the degree of grafting of humic compounds is significantly higher on the activated surfaces of burnt rock.
