Annotation	The aim of the research is to develop an efficient method for purification of the chromium containing wastewater by the means of the modified natural sorbents with improved sorption and mechanical properties. The structural and sorption properties of the above-mentioned sorbents have been investigated. The proposed nanomaterial in the form of the paste-like modified sorbent based on the bentonite clay of Tagansk deposit of East Kazakhstan and basalt fibers allows to reduce the chromium content to maximum permissible concentration (MPC). It gives the opportunity to discharge and recycle the purified water in the production.
