Sorry it's out de of my Agenda field

Asam Shad

Dear Sir,

I came across your question recently. I have learnt from my experiment which is related to advance oxidation processes (AOPs) that we cannot use the mentioned acid in phosphate buffer system. The chemicals which i used for adjustment of pH were H3PO4.H2O and Na3 PO4 , if the mentioned chemicals are used than the pH will not be maintained after the reaction. Exactly dont know whats the mechanism going on inside the buffer system but i knew it from my experiment that the mentioned chemicals cannot maintain the pH.

Stay blessed.
