Daftar Isi:
- Adsorption of Cr(VI) was performed using chitosan derivative, carboxymethyl chitosan-urea-glutaric acid (CMC-UGLU) with adsorption-fluidization method. CMC-UGLU synthesized from chitosan was reacted with chloroacetic acid, the productt obtained, carboxymethyl chitosan (CMC), was then characterized by FTIR spectroscopy. Adsorption of Cr(VI) was carried out with the variation of time, temperature and pH onto the fluidization bed with 200 mL solution of Cr(VI) with levels of 100 mg/L and 0.5 g CMC-UGLU by air blowing air from the bottom of the column. The results reveal that the adsorption capacity of CMCUGLU was 93.36% at the operating conditions which compares to the adsorption capacity of 92.89% of the adsorbent silica gelCMC-UGLU at the same conditions.
