Study on the Removal of Copper Ions from Water Using Eco-friendly Attapulgite/Chitosan Composites
In this work attapulgite and chitosan were employed to prepare composites as eco-friendly adsorbent.Study on the removal efficiency of the adsorbent for copper ions in aqueous solution was carried out.External factors such as the amount of attapulgite in the composites,temperature,initial concentration of copper ions,adsorption time and adsorbent dosage how to influence the removal efficiency of composites were investigated.The results showed that at room temperature,0.37g adsorbent can reach maximum adsorption rate,which the mass ratio of attapulgite and chitosan is l:l,the initial concentration of copper ions is 50mg / L and absorption time is 2h.
