Abstract
The problem of pollution of water spaces with heavy metals in Russia remains urgent with an increase in economic growth and production volumes at metallurgical enterprises. Plant agricultural waste can be used as sorbents for the extraction of heavy metal ions and oil products. The sorption properties of these materials are due to their chemical composition, namely the presence of lignin, cellulose and hemicellulose. Such vegetable waste includes almond shells, which remain in large quantities after processing almonds. Almond shell is a valuable biological resource and can be processed into a sorption material for wastewater treatment from heavy metal ions. This article discusses a method for obtaining sorption material from almond shells by chemical modification, and also determines its effectiveness in purifying a model solution containing copper ions.
