| 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。

| Abstract: | It is discussed that the influence of different oxidation state Fe(Ⅱ),Fe(Ⅲ)]of iron on the decomposition of H_2O_2 and the effect of stabilizers and chelants against H_2O_2 decomposition in this paper. According to the experiment, the iron-induced decomposition of H_2O_2 is significantly improved when pH value increases. The optimum dosage of Na_2SiO_3 and MgSO_4 which stabilized H_2O_2 against iron-induced decomposition is 0.1%.The effect of stabilizing H_2O_2 is better when stabilizers and chelants are combined. |
