Technology for producing activated carbons based on compact vegetable raw materials

The article presents the research on the development of highly active coal using domestic raw material base for soil restoration. It is shown that the feedstock is one of the main factors in forming quality indicators of carbon adsorbents, such as bulk density, parameters of porous structure, adsorption properties and mechanical strength. �ompact vegetable raw material, such as nut shell and fruit stone shells of peach and apricot, was used for manufacturing activated carbons (A�) meeting modern requirements. It was found that coal based on fruit stone shells of apricot and peach are on the same level with the A� based on coconut shell, and in many ways they are far superior to the contemporary commercially available domestic coal. An effective technique of restoring soil contaminated with pesticides through carbon-adsorption detoxification is suggested. The method comprises incorporating active carbon (A�) in the form of grains, powder, or aqueous suspension, into the soil, which provides absorption of soil pesticides. It is experimentally established that the use of activated carbon SRU-�A at a dose of 100 g/ha contributes to the overall effect of toxicity elimination, and this brand of activated carbon can be used to restore soil.
