摘要
对比了第四周期过渡元素离子对H_2O_2分解的催化活性,结果表明在pH值为11时,催化顺序为Co(Ⅱ)>Mn(Ⅱ)>Ni(Ⅱ)>Cr(Ⅱ)>Fe(Ⅱ);拟合了温度影响的回归方程;发现了在本文条件下,这些离子在相当小的浓度区域对H_2O_2有一定稳定作用。
This paper studied and contrasted the catalysing activity of some transition elements ions on the decomposition of H_2O_2. The result showed that at pH 11, its catalytic order is Co(Ⅱ)>Mn(Ⅱ)>Ni(Ⅱ)>Cr(Ⅲ)>Fe(Ⅲ). The regression equation for the effect of temperature was given. It was also found that under the conditions of this study, these ions at much lower concentration regioils have some stabilising effect on H_2O_2.
