摘要
研究了Fe(Ⅱ)、Fe(Ⅲ)对H2O2催化分解的影响以及保护剂、螯合剂的使用对H2O2的保护效果。通过实验得出:随着pH值升高,铁离子对H2O2的催化分解作用逐渐加剧;Na2SiO3和MgSO4同时使用且用量为0.1%时,对H2O2的保护作用最佳;保护剂与螯合剂联合使用,效果更好。
It is discussed that the influence of different oxidation state [Fe（ Ⅱ ）, Fe（ Ⅲ ）]of iron on the decomposition of H2O2 and the effect of stabilizers and chelants against H2O2 decomposition in this paper. According to the experiment, the iron--induced decomposition of H2O2 is significantly improved when pH value increases. The optimum dosage of Na2SiO3 and MgSO4 which stabilized H2O2 against iron--induced decomposition is 0. 1%. The effect of stabilizing H2O2 is better when stabilizers and chelants are combined.
