SORBENT CATALYST FOR PURIFYING NATURAL AND WASTE WATER AND METHOD FOR PRODUCTION THEREOF Russian patent published in 2012 - IPC C02F1/28 B01J20/20 B01J20/32 

FIELD: chemistry.

SUBSTANCE: inventions can be used in apparatus for purifying natural and waste water. The sorbent catalyst is obtained from schungite III which is ground to particle size 3-5 mm with carbon content of about 30%. After washing with water, the schungite is flooded with a solution consisting of a mixture of 5% HCl and 5% H₂O₂ solutions in ratio: 5% HCl - 50%, 5% H₂O₂ - 50%, and held in that solution for 8 hours. The schungite is then rewashed with water and dried at temperature of 105°C.

EFFECT: obtained sorbent catalyst has high sorption and catalytic properties and its use provides high efficiency and cost-effectiveness of the process of purifying natural and waste water.
