PREPARATION OF ANION-EXCHANGE CELLULOSE FOR THE REMOVAL OF CHROMATE

ABSTRACT The quaternary ammonium group containing cellulose was prepared by the one-pot method and applied for the removal of chromate (CrO42−) ions from aqueous solution. The prepared sorbent was characterized by using elemental analyzer and Fourier transform infrared (FTIR) spectroscopy....
