摘要
以太阳光为光源,利用草酸铁/过氧化氢体系对酸性棕SS进行光催化氧化脱色反应,研究了氯化钠、硫酸钠和硝酸钠对光催化氧化脱色性能的影响。结果表明:硝酸钠对酸性棕SS的光催化氧化脱色有一定的促进作用,氯化钠和硫酸钠对酸性棕SS的脱色均有不同程度的抑制作用,其中硫酸钠的抑制作用更显著。
In sunlight,sodium chloride,sodium sulphate and sodium nitrate were used for investigating their effects on photocatalytic oxidation decoloration of Acid Brown SS in water based on a ferric oxalate/hydrogen peroxide system.The results indicated that sodium nitrate had acceleration effect on photocatalytic oxidation decoloration of Acid Brown SS; sodium chloride and sodium sulphate had inhibition effects to some degree on decoloration of Acid Brown SS;the inhibition effect of sodium sulphate was more significant.
