FIELD: ecology; sorption cleaning of aqueous solutions.
SUBSTANCE: proposed sorbent is magnet-controllable sorbent on base of magnetite with reaction-able groups immobilized on its surface. Method of production of sorbent includes treatment of magnetite suspension at first stage by amino propylene triethoxy silane or amino ethoxy siloxane; at second stage it is treated with silicon organic hydrophobic fluid; then sorbent is dried at temperature of 150-200 C. Invention gives examples of cleaning water from petroleum products by proposed sorbent.
EFFECT: enhanced efficiency of cleaning.
