Abstract: the paper presents the results of the study of the possibility of using peanuts waste processing as a sorption material. The literature data on the use of numerous materials as sorbents are given. Physico-chemical and structural-morphological features of peanut shells were investigated. The object of the study was methylene blue dye as a widely known and used substance, and the sorption capacity for methylene blue is an important characteristic of industrial sorbents. The adsorption capacity of the material is calculated and the adsorption isotherm is constructed. The sorption capacity of the original peanut shell by methylene blue was 0.22 mmol/g.
Keywords: adsorption, methylene blue, husk of the peanut, the efficiency of cleaning
