The opportunity of low-cost native material using for removal of copper ions and basic dye Methyl violet has been shown. Sorption on isolated from wheat bran dietary fiber has been studied from solutions with low concentration. Ion-exchange ability of sorption material is ascertained to be conditioned by carboxylic group’s presence in dietary fiber composition what has been confirmed by FTIR spectra. Neutral salts concentration influence on sorption capacity toward copper ions has been demonstrated in static condition. Sorption of Cu(II) ions and especially of basic dye Methyl violet occurred rather quickly in conditions of experiment. The sorption of basic dye has been studied in dynamics. The column process allowed complete purifying filtrate from dye.
