CHEMICAL-EXPERIMENTAL STUDY OF THE EXTRACTION OF HEAVY METAL IONS FROM AQUEOUS SOLUTIONS USING NATURAL SORBENTS

Abstract

This article studied the possibility of using natural sorbents in order to effectively isolate heavy metal ions from aqueous solutions. The main object was considered copper and lead ions from heavy metals, which contribute significantly to the pollution of water resources. To reduce their concentration, affordable and environmentally friendly sorbents such as bentonite and activated carbon were used. During the study, the main factors affecting the sorption process were analyzed in detail, in particular, the type of sorbent, sorption time and concentration of ions of the starting metals. Practical results have shown that natural sorbents can effectively absorb heavy metal ions and their use in water treatment technologies gives high results. The data obtained indicate that natural sorbents can be used in the development of environmentally friendly and cost-effective cleaning methods.
