二氧化钛改性羊毛光催化降解染料性能的研究

Research on photocatalytic degradation of dye performance with titanium dioxide modified wool

采用在光化学反应仪中,对用钛酸四丁酯、钛酸异丙酯和硫酸钛尿素为钛源水热合成的改性羊毛在罗丹明B溶液中,探究二氧化钛在光照下加快其对染料的分解,为了研究该化学反应过程,进而探究罗丹明B标定曲线。结果证实,用来自不同钛源处理的羊毛对于染料降解情况不同,钛酸异丙酯改性羊毛对染料的降解率最好,同时对光催化降解率高的改性羊毛做2次、3次光催化,可以看出在紫外照射下,钛酸异丙酯改性羊毛的2次、3次光催化依然很好,符合国家环保政策。

This study was used in the photochemical reaction instrument,using tetrabutyl titanate,titanate isopropyl and titanium sulfate and urea treated modified wool in rhodamine B solution,explore titanium dioxide in the light accelerated the fuel decomposition. Secondly,in order to study the chemical reaction process,and then explore the rhodamine B calibration curve. The results showed that with wool from different source of titanium processing degradation is different for dye,isopropyl titanate modified wool for the degradation of dye rate is best at the same time,high light catalytic degradation rate of modified wool do photocatalytic of twice,three times. It can be seen under ultraviolet irradiation,isopropyl titanate modified wool twice,three times of photocatalytic is still very good,compound national environmental protection policies.
