METHOD FOR CATALYTIC DECOMPOSITION OF HYPOCHLORITE IONS Russian patent published in 2016 - IPC C01B11/06 C02F1/00 B01J23/755 B01J27/232 B82B3/00

Abstract RU 2601450 C1

FIELD: chemistry.

SUBSTANCE: invention relates to chemical engineering, specifically to a method of purifying industrial sewage water from hypochlorite ions, formed during chlorination of lithium, sodium and calcium hydroxides. Method for catalytic decomposition of hypochlorite ions involves contacting a solution containing hypochlorite ions with a nickel-containing catalyst in form of particles at temperature of 32-67 °C, with extraction of gaseous oxygen. Nickel-containing catalyst used is basic nickel carbonate, dispersed on a nanoporous composite carbon material, containing as binder a fluoroplastic suspension at ratio of components, wt%: nanoporous composite carbon material 49-54, fluoroplastic suspension 5-9, basic nickel carbonate - balance.

EFFECT: efficient purification from hypochlorite ions with high rate of decomposition and at lower temperatures.
