Abstract
The proposed method for producing sorbent for purification of wastewater from organic admixtures comprises treatment of particles of inorganic material. As inorganic material volatile coal ash is used. On which surface in aqueous suspension thereof applied at first solution of sodium carbonate at a weight ratio of Na2CO3/ash=(0.1-0.4):1 for dry substance, and then the solution of AlCl3 at weight ratio of Na2CO3/ AlCl3=(3-4):1 as counting for cation.
