Abstract

An actual trend in applied ecology is the development and implementation of innovative environmental protection technologies. Modern methods for extracting heavy metal ions from industrial wastewater are quite diverse. The purpose of the study was to develop and justify new technologies for purification of aqueous media, including adsorption purification, from heavy metal ions (by the example of Ni2+ and Cd2+ ions). Laboratory studies have established that the degree of adsorption extraction of Ni2+ ions by the sorption material from bentonite modified with carbon nanotubes and fired at a temperature of 550 °C increases by 13-14% due to its activation with 18% HCl solution and 38% CaCl2 solution, and the degree of adsorption extraction of Cd2+ ions with this activation of the sorbent, it increases by 16-17%. A technological scheme of a water purification station is proposed, which includes highly efficient adsorption filters with sorption material from bentonite of the specified modification and acid-salt activation.
