Abstract

The invention relates to a process for obtaining a catalyst for water purification from organic compounds and may be used in the sterilization and degasification of aqueous solutions for food industry.The process includes utilization of the montmorillonite-type clay, purification thereof from quartz and cristobalite by repeated sedimentation into a bath with ultrasound and from organic inclusions by calcination at the temperature of 450°C during 3 hours in the airflow, with modification thereof in the salt solution by ion exchange with cations, at the same time it is used clay with cation-exchange capacity of 1,10...1,15 mg-equiv./g, and modification is carried out by impregnation of the purified clay with 1M solution of Na+ salts or one of the transition metals, namely Fe+2, Co+2, Ni+2, Cu+2,in the ratio, respectively, of 1:25, by agitation during 4...5 hours, with repeated dialysis in deionized water at the room temperature, then the clay is centrifugated and dried at 60°C during 10...12 hours.
