Abstract

The level of the sorption of model mixture components composed of phenol, aniline, benzene, toluene and brombenzene by activated charcoal obtained from the Circassian walnut shell has been assessed by means of reversed-phase high performance liquid chromatography (RP-HPLC) method. The acetonitrile–water mixture (50:50 by volume) has been applied as mobile phase. The samples of activated charcoal have been prepared by means of dry distillation. Caustic soda, sodium carbonate, and orthophosphoric acid have been used as activators. The introduction of activators has been carried out by means of exposing the shell samples in the solutions of indicated reagents. The influence of the additional treatment of the obtained samples of activated charcoals by nitric acids on their sorption properties has been studied as well.
