做光催化降解的时候由于材料改性前后吸附性能不一样导致反应初始浓度不一样 请问这样会不会影响反应速率常数?是不是应该控制在吸附完之后浓度是一样的?但是在Heterogeneous photocatalytic oxidation of cyanide ion in aqueous solutions at titanium dioxide powder,S. N. Frank and A. J. Bard: J. Am. Chem. Soc. 99 (1977) 303.)中,对于光降解效果有这样一句描述:The results shown in Figure 1 for high intensity radiation show that the rate of CN- disappearance was essentially independent of the CN- concentration.意思是降解速率和浓度无关吗?
