of DCA (TOC removal) after 4 hours of illumination using the photocatalyst 0.35
Ag- 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,
with chloride ion addition in set B before the third run and with
intermittent washing between runs (set C). The photocatalyst loading was 0.5 g/L
and the light intensity Einstein .
