N2 - Research into extraction kinetics is one of the crucial factors in a technological process. Extraction is used predominantly when working with organic feedstock. The study of the kinetics of extraction of a substance is a complex process, which is influenced by a large number of factors. This paper presents an analysis of one of these factors, namely the influence of reverse sorption on the process of substance release from the matrix. Sorption can directly affect the intraparticle diffusion constants and, consequently, the rate of release of the substance. Using buckwheat husk as an example, its sorption capacity was assessed to assess the sorption factor on the rate of melanin release. To select the optimal parameters of the chemical process, the experiment was carried out at temperatures of 40, 50, and 60 degrees Celsius. The Axelrud and Baker–Lonsdale equations were used to describe the kinetic models.
