过氧化氢催化活化体系对HD消毒性能的研究

Decontamination of HD by the Catalytic System of Hydrogen Peroxide Solution

摘要: 传统含氯消毒剂消毒效率高，但往往腐蚀性较强，对环境和人类健康有一定影响；含氧消毒剂尤其是过氧化物作为绿色消毒剂成为研究的热点。基于过氧化氢与胍类活化剂和金属盐催化剂反应生成更高活性物质的原理，以30% H₂O₂为主剂，考察有机活化剂氨基胍硫酸盐、金属盐催化剂钼酸钠以及表面活性剂等助剂对该体系消毒HD效果的影响，优化获得最佳消毒条件；在室温涡旋震荡条件下，消毒剂溶液与HD液滴体积比50:1，消毒反应15 min消毒率达到99.9%以上。

Abstract: The traditional chlorine decontaminants with the high decontamination efficiency had usually a certain impact on the environment and human health due to their strong corrosivity. But the decontaminants composed of peroxide hydrogen as green decontaminants, had become a research hotspot. In the paper, the principle that hydrogen peroxide reacts with guanidine activator and metal salt catalyst to produce higher active substances would be discussed. Meanwhile, the factors that influenced the decontamination efficiency had investigated, such as the main agent peroxide hydrogen with the concentrate of 30%, the organic activator aminoguanidine sulfate, metal salt catalyst sodium molybdate, surfactants and so on. As a result, the optimized decontamination situation had been attained. With the vortex vibration at room temperature, the decontamination rate reached over 99.9% in 15 minutes when the volume ratio of decontaminant solution and HD drops was 50:1.
