目的:研究水中污染物双酚A的紫外光催化降解。方法:考察了紫外光催化降解条件影响等因素。结果:紫外光降解条件:BPA为40 mg/L水溶液1 L;加入H2O230 ml;Ti O2加入量1.0 g;紫外灯照射功率为60W,24 h可降解至最初含量的1.2%。结论:通过合适的紫外光催化条件,水中双酚A能够在短时间内被有效降解,该项研究对工厂排污、城市污水环保处理具有一定的参考意义。
Objective: To study ultraviolet photocatalytic degradation of bisphenol A in water. Methods: The effects of UV photocatalytic degradation conditions and other factors were investigated. Results: The degradation conditions of UV light were as follows: BPA was 1 L in 40 mg / L aqueous solution; 30 mL of H2O2 was added; the amount of Ti O2 added was 1.0 g; UV irradiation power was 60W and degraded to 1.2% of initial content after 24 h. Conclusion: The bisphenol A in water can be effectively degraded in a short period of time by suitable UV light catalytic conditions. This study is of certain reference significance for the treatment of factory effluent and municipal wastewater.
