摘  要:
以孔雀石绿为模型污染物考察壳聚糖量子点作为光催化降解剂的应用。结果表明,壳聚糖量子点对孔雀石绿光催化降解去除效率高,反应速率快,向20 mg/L孔雀石绿溶液中加入100 mg/L壳聚糖量子点,紫外光辐射反应90 min,去除率高达94.3%。孔雀石绿首先通过壳聚糖量子点表面壳聚糖的吸附作用富集在量子点的表面,再通过量子点的光催化性能进行催化氧化。壳聚糖量子点可以作为降解剂用于光催化降解领域。

摘  要:
Photocatalytic degradation of malachite green(MG),used as a model pollutant,by chitosan coated quantum dots(QDs) was investigated. The results showed that the removal efficiency of MG by QDs was high,and the reaction rate was fast. After illumination for 90 min,the removal efficiency of MG solution with a concentration of 20 mg/L by QDs with concentration of 100 mg/L was 94.3%. Firstly,MG absorbed on the surface of QDs,and then the catalytic oxidative reaction were performance through the catalytic properties of QDs. The QDs could be used as a kind of photocatalyst in the field of degradation.
