Obtaining Sorption Material from the Leaves of Aésculus Hippocastanum L.

Abstract

Using waste of different genesis as sorption materials allows solving several problems at once such as decontamination of waste and reduction of production costs. The physicochemical properties of the products of thermal modification of Aésculus hippocastanum L. leaves, which are promising raw materials for the sorption material, were studied. It is established that the optimal modification temperature is 250 oC. At higher temperatures, cellulose and levoglucosane are decomposed with a decrease in the total percentage of carbon from 62 to 10 mass.%. High purification efficiency of model emulsions containing industrial oil (91 and 97%) is achieved even at heat treatment temperatures of 150 and 250 oC, respectively. With further increase in temperature the cleaning efficiency practically does not increase, therefore, a further increase in firing temperature is not rational.
