用ＵＶ－Ｖｉｓ吸收光谱和差谱考察了以ＤＢＣ－偶氮羧为主的５ 种偶氮化合物在纳米ＴｉＯ２ 表面光降解的动力学行为和电子转移历程， 载荷子的捕获经历一个中间过程， 最终矿化为无机物． 按误差补偿理论拟合的中间体峰形曲线和实验ｃ～ｔ图平行吻合， 获得了相应的动力学参数． 推测了电子转移的可能途径
The kinetic behavior and electron transfer of photodegradation of 5 azo compounds mainly containing DBC-azo carboxylates on the surface of nano-TiO2 were investigated by UV-Vis absorption spectra and difference spectra. The capture of charge carriers underwent an intermediate process and the final ore Into inorganic. According to the error compensation theory fitted intermediate peak shape curve and experiment c ~ t parallel agreement, obtained the corresponding kinetic parameters. We speculate on the possible ways of electron transfer
