We applied solar photo catalysis for the treatment of pollutants in saline water. The presence of chloride ions significantly reduce the performance. Is there any proper solution to overcome this problem?
OH radical react with chloride anion to form chlorine atom, which is highly reactive. Your significant reduce of performance is likely due to other reasons.
You can use any cationic polyelectrolyte to remove the chloride anion through complexation using Polyethyleneimine or chitosan. You need to adjust the pH.
Hi S. Feroz,
I think that pH is also a factor that greatly affects the photocatalytic ability of a material (providing OH- or H + ions with the reaction process). Adding H2O2 as an electronic acceptor is also a good way. However, to reduce the effect of chloride ions, it is better to adjust the pH of the solution.
Best wish.
Quan-Doan Mai.
