摘要
在纳米二氧化钛悬浮体系中,以紫外汞灯为照射光源,考察了光照辐射强度、纳米TiO_2的投加量、反应体系温度、投加葡萄糖等对光催化还原Cu(Ⅱ)的影响。实验结果表明,纳米TiO_2在300 W紫外汞灯的照射下光催化还原Cu(Ⅱ)的速度高于115 W;控制反应体系温度35℃下TiO_2的最佳用量为3 mg/L;投加葡萄糖促进了TiO_2对Cu(Ⅱ)的光催化还原效率,且随着葡萄糖量的增加而增大。
The influence of photocatalytic reduction of Cu （II） by nanometer TiO2 in suspending and under ultraviolet lamp is studied through changing the intensity of radiation, the quantity of TiO2, the system of temperature and glucose. The results show that Cu （II） is effectively removed by nanometer TiO： under 300 W ultraviolet lamp, and its reaction speed is quicker than 115 W. Under controlling the temperature of reaction system in 35 ℃, the optimal quantity of TiO2 is 3 mg/L. Dosing glucose promotes the photocatalytic reduction efficiency to Cu （ II ） effectively by TiO2, and Its efficiency increases with the increase of the amount of glucose.
