Photocatalytic degradation of sulphur containing organics in water was substantially accelerated by the in-situ removal of sulphur oxide species formed by the dye degradation as metal sulfate precipitates. The significant enhancement of the degradation of methylene blue (C₁₆H₁₈ClN₃S) and acid yellow 42 (C₃₂H₂₄N₈Na₂O₈S₂), as examples of sulphur containing organics, was achieved when the reactions were conducted in the presence of alkaline earth cations (such as Ca²⁺, Sr²⁺, and Ba²⁺).

通过原位去除降解产物来促进有机物的光催化降解

通过原位去除由染料降解形成的金属硫酸盐沉淀而形成的氧化硫物质，大大促进了水中含硫有机物的光催化降解。当反应进行时，亚甲基蓝（C ₁₆ H ₁₈ ClN ₃ S）和酸性黄42（C ₃₂ H ₂₄ N ₈ Na ₂ O ₈ S ₂）的降解显着增强。在碱土金属阳离子（例如Ca 2 ⁺，Sr ²⁺和Ba ²⁺）存在下进行。
