摘要
过氧化氢(H_2O_2)的稳定性受温度、浓度、pH值,某些阴阳离子等因素的影响,对此已有不少报道[1,2,3]。其中多数报道只限于研究某个pH值、温度和浓度及某种阴、阳离子的影响情况[1～5]本文在H_2O_2初始浓度为0.05mol/L、P、pH值为11时,研究对比了几种重金属离子在不同温度下的催化活性;温度为70℃时,几种重金屑在不同浓度下的催化活性。
This paper,with the decomposition rate of hydrogen peroxide in 30 minutes,studied and contrasted the catalysing activity of some certain heavy metal ions to the decomposition of hydrogen peroxide.The result showed that its catalytic order is Cu^(2+)>Co^(2+)、Ag^+>Mn^(2+)>Ni^(2+)、Pb^(2+).It was also found that in the alkaline solutions, under higher temperature and with certain concentration,some heavy metal ions,to some extent,have some stabilising effect to hydrogen peroxide.
