The paper presents the results of investigating the possibility of increasing the sorption capacity of peanut peel after heat treatment at 300°C for 30 minutes. World peanut production is about 40 million tons for 2017-2018. The peel remaining after peanut processing is not used and it is unused waste. For research peanuts were taken growing in the valley of Aleppo (Syria). It was established that after heat treatment, the peanut peel surface becomes more prominent, which improves its sorption properties. During the heat treatment, the charring of the plant fibers that make up the peel occurs, as a result of which the surface of the material is covered with a layer of soot and becomes black. The black color has the greatest intensity during heat treatment at 300 oC. At lower roasting temperatures, the carbonization of the fibers is insufficient.At higher temperatures, the carbon layer is burning with the formation of CO2.
