After Fenton's reaction, a pH adjustment would be made to 7 to precipitate the Fe species out. However, how do i test for the Fe species/the Precipitated compound?
thanks for your suggestion. Just want to check the condition of the precipitate if in the solids form would XPS still work? or would I need to acidify it to dissolve the Fe precipitate. Would this method be able to identify the Fe complexes and the quantity as well?
