摘要 目的 通过试验对邻苯二甲醛消毒剂的杀菌效果进行科学评价。方法 采用悬液定量杀菌试验,观察其杀菌效果及稳定性。结果 在20~21℃条件下,以5664mg/L邻苯二甲醛对大肠埃希菌、金黄色葡萄球菌和白色念珠菌作用1min,平均杀灭率达99.99%;对枯草芽胞杆菌黑色变种芽胞作用60min和90min,平均杀灭率分别为99.94%和100.00%,该原液放置于56℃条件下2周,邻苯二甲醛含量下降率为3.27%。结论 邻苯二甲醛消毒剂具有良好杀菌效果,稳定性好。 OBJECTIVE To evaluate the germicidal efficacy of phthalaldehyde disinfectant. METHODS Suspension quantitative bactericidal test was used to observe its bactericidal efficacy and stability. RESULTS The temperature was 20-21℃. The results showed that the average killing rates of Escherichia coli, Staphylococcus aureus and Candida albicans exposed to the solution containing 5 664mg/L phthalaldehyde for 1 min were 99.99 %, and the average killing rates of spores of Bacillus subtilis var. niger exposed to the solution containing 5 664mg/L phthalaldehyde for 60 min and 90 min was 99.94 % and 100 %, respectively. When its stock solution was stored at 56℃ under airtight condition for 2 weeks, the content of phthalaldehyde decreased by 3. 27%. CONCLUSIONS The phthalaldehyde disinfectant is a good and stable bactericide.
