During ozonation pH tends to lower during ozonation due to the formation of carboxylic acids. What the pH controlled during runs. If not, the results of Fig. 6 may be meaningless as initial pH is not enough to characterize reaction conditions. This point is critical and must be carefully addressed ,
一般都会注明初始pH,过程中肯定会变化,有时需要研究反应过程中pH变化,除此一般都是初始
审稿人回复的,从哪个角度回答比较好

请问大神做过催化臭氧自我分解的实验吗?
请问大神有没有做过在水溶液中催化臭氧分解的实验?如果加入的催化剂是对吸光度有影响该怎么处理?
控制初始pH就可以。
控制pH值是因为臭氧在水中的分解速度随PH值提高而加快,pH值提高一个单位,臭氧分解大约会快三倍,从而产生更多的.OH。同时,臭氧吸收率在碱性条件下优于酸性条件。臭氧氧化过程中,有机物氧化成小分子有机酸醛类物质,所以pH值随氧化过程进行呈下降趋势。
