Removal of Cr(VI) from Water Using Attapulgite/Chitosan Composites

Abstract:

In this work attapulgite and chitosan were employed to prepare composites as eco-friendly adsorbent. Study on the adsorption efficiency of the adsorbent for Cr (VI) in aqueous solution was carried out. External factors such as the amount of attapulgite in the composites, initial concentration of Cr (VI), adsorption time and adsorbent dosage how to influence the adsorption efficiency of composites were investigated. The results showed that 0.63g adsorbent can reach maximum adsorption rate, which the mass ratio of attapulgite and chitosan is 0.8:1, the initial concentration of copper ions is 100mg / L and absorption time is 30min. Isotherm data fitted well to the Langmuir isotherm model.
