METHOD OF PRODUCING SORBENT FOR DICHROMATE IONS Russian patent published in 2016 - IPC B01J20/32 C08G73/02

Abstract RU 2596256 C1

FIELD: chemistry.

SUBSTANCE: invention relates to sorption technologies. Disclosed is a method of producing sorbent of dichromate ions, consisting of inert support and active sorbent polymer layer of polyaniline. Sorbent layer is produced by oxidative polymerisation of aniline on a support in presence of hydrochloric acid. Support used is rubber crumbs with particle size of 0.125-1.0 mm. Oxidative polymerisation is carried out with molar ratio of aniline to ammonium persulphate and to hydrochloric acid equal to 1:1.25:(0.12-0.47). Weight ratio of aniline to rubber crumbs is (3.32-0.23):1.

EFFECT: simplified process with increase of its sorption capacity with respect to dichromate ions.
