摘要
经检测，过氧化氢复方消毒剂的杀菌效果，随其浓度增大、作用时间延长、温度升高而加强，有机物影响较小，溶液ｐＨ值无明显影响。该消毒剂对布表面细菌杀灭效果较好，对玻璃、塑料表面者略差。其原液贮存于室温下９个月，过氧化氢浓度下降８７７％。该消毒液对棉布、金属损坏作用较小，对皮肤无刺激，属无毒类。
he germicidal influencing factors, corrosiveness and toxicity of compound disinfectant of hydrogen peroxide were observed experimentallyThe results indicated that the germicidal efficacy of this disinfectant increased with increasing concentration, exposure time and temperature Organic substance only caused decrease in efficacy of the disinfectant at low concentration, while pH value of the solution had no obvious influence This disinfectant had good efficacy in killing bacteria on surface of cloth, while its efficacy in killing bacteria on surface of glass or plastics was slightly lower The concentration of hydrogen peroxde in its stock solution decreased by 877% after storing at 15～25℃ for 9 months Immersion of pure cotton cloth in its 2% solution for 20 times of 2 hr each did not influence significantly the rupture strength of both warp and woof of cloth Its 1∶5 diluted solution was non-corrosive to carbon steel, aluminum and stainless steel, and was essentially non-corrosive to brass Its oral LD50in mice was >50 kg/kg It is inirritative to skin
