摘要：
Azo dyes are not efficiently removed in water treatment. So the development of excellent absorbent is significant important for environmental protection. In this study, ceria is successfully immobilized on 40-60 mesh sand by using a simple method of sol-gel. And then research the effect of absorption on azo dyes in waster using immobilized CeO2 (ICe). The ICe absorbent displays high removal efficiency for AB10 (one typical kind of azo dyes) in waste water. In addition, after absorbing, concentration and toxicity of azo dye decreased and the absorbent easily separation from water which indicates that the technique is a promising post-treatment process to improve water quality.
