Abstract
The possibility of sorbent obtaining from the waste of plant origin, the peach shell, is considered.The physicochemical characteristics of the modified sorbents made from peach shells and their applications for purifying gas-air mixtures and sewage from toxic compounds are studied.According to preliminary data, the heat-treated peach shell, used as a sorbent and filter, is an effective cheap and available material for the treatment of wastewater and gas emissions.The complex of classical and modern methods of analysis is considered and characterized: elemental analysis, differential thermal, IR spectroscopic, X-ray structural, as well as other methods of study of physical-chemical and structural sorption properties.Based on experimental results, it was established that the sorbent on the base of modified sorbent prepared by chemical modification, followed by thermal activation in the atmosphere of carbon dioxide, has a porous structure.
