Abstract
The optimum conditions for the synthesis of enterosorbents of birch bark bast were determined by experimental and calculation methods. The regression equations describing the dependence of characteristics of enterosorbents from conditions of its synthesis were obtained. The optimum conditions for the preparation of an enterosorbent with the maximum sorption activity for methylene blue and containing less than 5 mass % of water soluble substances were calculated using these equations: NaOH concentration of 1.5 mass %, a temperature of 80 °C and treatment duration of 60 min. Calculated values correlate well with experimentally obtained results.
