摘要
采用自制的多金属氧酸盐Zn1.5PW12O40纳米管作为催化剂和分子氧作为氧化剂的催化氧化技术进行碱性藏花红的降解实验。结果表明:Zn1.5PW12O40适合用作催化剂,中空结构,杂多酸型,纳米级;空气氧化体系中的催化氧化最佳反应时间为4h,降解率78%、降解速率665μg/h;催化剂的活性和稳定性均较高,循环使用4次时,降解率仍>65%。
The technology of catalytic oxidation is studied for degrading safranine T.The self-made polyoxometalate Zn 1.5PW 12O 40 nanotube is used as the catalyst and dioxygen is used as the oxidizer.The results show:Zn 1.5PW 12O 40 is sutiable for catalyst,with the structure of the Zn 1.5-PW 12O 40 being hollowed,the type of the Zn 1.5PW 12O 40 being affiliated to the type of heteropoly acids,and the scale of the Zn 1.5PW 12O 40 being nanometer-scale;in the oxidation system of air,the optimum reaction time is 4 hours,and correspondently the degradation rate and the degradation velocity are respectively 78% and 665 μg/h;the activity and stability are both high,and when the circulation times are four,the degradation is still 65%.
