摘要
采用水热法制备锗酸锶晶体纳米线,并研究了其对龙胆紫的光催化性能。结果表明:随着光催化时间的延长和锗酸锶纳米线用量的增加,龙胆紫的降解率均呈上升趋势;但随着龙胆紫溶液初始浓度的增加,其降解率逐步降低。在光催化时间4h、锗酸锶纳米线用量10mg、龙胆紫溶液初始浓度10mg/L的条件下,锗酸锶纳米线光催化降解龙胆紫的效果最好,龙胆紫的降解率可达89.59%。
The strontium germinate crystal nanowires were prepared by hydrothermal method, and their photocatalytic performance for degrading gentian violet was investigated. The results show that the degradation rate of gentian violet increases by prolonging the photocatalysis time and increasing the dosage of strontium germinate crystal nanowires, but gradually decreases with the increase of initial concentration of gentian violet solution. Under the conditions of photocatalysis time of 4 h, strontium germinate nanowires dosage of 10 mg and initial concentration of gentian violet solution of 10 mg/L,the optimal photocatalytic effect of the strontium germinate nanowires for degrading gentian violet can be obtained, with a degrada- tion rate of 89. 59%.
