FIELD: chemistry.
SUBSTANCE: invention relates to production of sorbents for extracting mercury compounds from aqueous solutions Disclosed is a method of producing a sulphur-containing sorbent which includes polycondensation of sodium polysulphide with an organochlorine compound on the surface of petroleum coke particles. The organochlorine compound used is 1,4-dichlorobutyne-2.
EFFECT: method enables to obtain a sorbent with high mercury activity.
