Surface| Summary: | According to the results of mathematical processing of the obtained experimental data an adequate statistical model of the modification process of bleached cotton fiber with copper ferrocyanide solutions were obtained. The optimal values of the process parameters using Harrington's desirability function were determined. It was found out that the optimal parameters that allow to obtain an effective combined sorption materials with optimum content of inorganic component in the volume of the organic bulk and with high sorption capacity towards radiocaesium, are the modifier concentration of 4 g/l and a process temperature of 90 oC. However, taking into account the specific values of the recovery rate of caesium and distribution coefficient, that characterizing sorption and selective ability ferrocyanide mass, determined optimal parameters are 1 g/l and 90 °C respectively. |
