摘要
为了定量研究稳定性固体二氧化氯的杀菌效果,采用五步碘量法对实验室制取的稳定性固体二氧化氯消毒剂进行了有效成分的测定,并采用悬液定量杀菌法对其杀菌力做了系统的研究。实验选用大肠杆菌和金黄色葡萄球菌分别作为革兰氏阳性菌和革兰氏阴性菌的代表菌种,用含50、100、200mg/L的二氧化氯消毒剂的水溶液对实验菌作用1、3、5min,实验结果平均杀灭对数值均≥4.00。可以表明,该粉状消毒剂杀菌效果理想,对革兰氏阳性菌和革兰氏阴性菌均有良好的杀灭效果。
In order to quantitatively study the sterilization effect of solid chlorine dioxide antiseptics,the effective ingredients of the self-made chlorine dioxide example was determined by the five-step iodometry and the disinfection effect was systematically researched by the quantitative germicidal test.The sterilization effect was reserched using Escherichia coli and Staphylococcus aureus as the representative strains of Gram-positive bacteria and Gram-negative bacteria strains by acting on the test strains with the 50,100,200mg/L chlorine dioxide solutions for 1,3,5min.The result showed that the average killing logarithm values were all greater than or equal 4.00.The experiments results show that as an antiseptic powder chlorine dioxide has high effect and low toxicity, and good for killing Gram-positive bacteria and Gram-negative bacteria.
