Abstract

The main objective of the present study was to investigate the efficiency of titanium dioxide (TiO₂) assisted photocatalytic degradation (PCD) process for the removal of ammonium-ammonia (NH₄⁺-NH ₃) from the aqueous phase and in the presence of co-pollutants thiosulfate (S₂O₃^2-) and p-cresol (C ₆H₄CH₃OH) under varying mixed conditions. For the NH₄⁺-NH₃ only PCD experiments, results showed higher NH₄⁺-NH₃ removal at pH 12 compared to pH 7 and 10. For the binary NH₄⁺-NH ₃/S₂O₃^2- studies the respective results indicated a significant lowering in NH₄⁺-NH ₃ PCD in the presence of S₂O₃^2- at pH 7/12 whereas at pH 10 a marked increase in NH₄⁺-NH ₃ removal transpired. A similar trend was noted for the p-cresol/NH₄⁺-NH₃ binary system. Comparing findings from the binary (NH₄⁺-NH₃/S ₂O₃^2- and p-cresol/NH₄ ⁺-NH₃) and tertiary (NH₄⁺-NH ₃/S₂O₃^2-/p-cresol) systems, at pH 10, showed fastest NH₄⁺-NH₃ removal transpiring for the tertiary system as compared to the binary systems, whereas both the binary systems indicated comparable NH₄⁺-NH₃ removal trends. The respective details have been discussed.
