摘　　要：由于双氧水的优良特性及其广泛的用途,其在化工行业的使用已经非常广泛。当前仍有部分企业对双氧水的安全使用方法掌握不充分,涉及双氧水的事故也时有发生。主要针对双氧水的安全使用条件研究以及双氧水的安全使用策略进行讨论。介绍了使用DSC(差示扫描量热仪)仪器以及化学实验室常规设备研究双氧水的热安全风险,研究了双氧水在不同Fe^(2+)含量、不同pH值、不同浓度条件下的分解温度与放气量。经过研究,Fe^(2+)会促进双氧水分解并使双氧水分解温度降低,随着pH值的升高双氧水的分解温度会先上升再下降,随着浓度的升高双氧水的分解温度会降低。结合化工行业的常用安全方法,给出了一些关于双氧水安全使用的建议与策略。Due to the excellent characteristics of hydrogen peroxide and its wide range of uses,hydrogen peroxide has been widely used in the chemical industry.At present,there are still some enterprises that do not fully grasp the safe use of hydrogen peroxide,and there are safety accidents about hydrogen peroxide.The study on the safe use conditions of hydrogen peroxide and the safe use strategy of hydrogen peroxide are discussed.The thermal safety risk of hydrogen peroxide was studied by DSC(Differential Scanning Calorimeter)instrument and conventional equipment in chemistry laboratory.The decomposition temperature and exhaust volume of hydrogen peroxide were studied under different Fe^(2+)content,pH value and concentration.After research,Fe^(2+)will promote the decomposition of hydrogen peroxide and reduce the decomposition temperature of hydrogen peroxide.With the increase of pH value,the decomposition temperature of hydrogen peroxide will first rise and then decline,and with the increase of concentration,the decomposition temperature of hydrogen peroxide will decrease.According to the common safety methods in chemical industry,some suggestions and strategies on the safe use of hydrogen peroxide are given.
