Adsorption to Cu²⁺ in Waste Water with Chitosan Intercalation Bentonite

Abstract:

The development of new water pollution control technology, particularly the development of high efficiency and low cost adsorbents is imperative. A compound adsorbent was prepared with the combination of chitosan and bentonite. Bentonite was added in chitosan slurry of 95% the degree of deacetylation to prepare adsorbent which mass ratio is 1:5. Its absorptivity toward Cu²⁺ was studied. The results show: the dosage of the adsorbent is 14 g/L,the mass concentration of Cu²⁺ in wastewater does not exceed 180 mg/L,the pH value range from 6 to7,the adsorption equilibrium time is about 9 h and Cu²⁺ removal efficiency is over 97%.The low cost of adsorbents can be used to control industrial waste water containing copper.
