Removal
DCA (TOC removal) after 4 hours of illumination using the colloidal- photocatalyst at pH 3 in 3 consecutive runs (1st run ,
2nd run , and 3rd run ) the production efficiency after 4 hours of illumination is also shown (1st run ,
2nd run , and 3rd run ) in set A
and with chloride ion addition before the third run (set B). The photocatalyst loading
was 0.5 g/L and the light intensity Einstein .
