摘要: 目的:了解市售两种品牌免洗消毒液中主要有效成分的稳定性和消毒效果。方法:采用紫外分光光度法与气相色谱
法测定两种免洗消毒液使用后,主要有效成分乙醇和聚六亚甲基双胍盐酸盐的残留与时间的关系,同时采用现场消毒实验
检测消毒液使用后不同时间段的杀菌率。结果:100 min内两种免洗消毒液中乙醇的含量分别下降了83.10%和58.83%,聚
六亚甲基双胍盐酸盐浓度分别上升267.94% 和88.57%。现场消毒实验表明两种消毒液在前40 min 均有非常高的杀菌率
(99.89%,99.75%),且消毒液A 20 min时杀菌效果最好,消毒液B 40 min时杀菌效果最好,60 min时消毒液A杀菌效果明显
下降而消毒液B依旧保持较高水平。结论:相对而言,消毒液B的消毒效果较消毒液A略低,但消毒液B成分更为稳定,杀
菌维持时间比消毒液A长。

Abstract: Objective: To understand the stabilities and disinfection effects of main effective ingredients in two brands of disposable
disinfection solutions on the market. Methods: Using ultraviolet spectrophotometry and gas chromatography to determine the
relationship between the residues of the main effective components, i.e. ethanol and polyhexamethylene biguanide hydrochloride, and time after the use of two kinds of disposable disinfectants. At the same time, field disinfection experiments were also carried out to monitor the sterilizing rate of disinfectant in different periods after use. Results: Within 100 minutes, the content of ethanol in two
kinds of disinfectants decreased by 83.10% and 58.83% respectively, while the concentration of polyhexamethylene biguanide
hydrochloride increased by 267.94% and 88.57% respectively. Field disinfection experiments showed that both disinfectants had very
high sterilizing rate(99.89%, 99.75%)in the first 40 minutes. Disinfectant A had the best germicidal effect at 20 minutes, and
disinfectant B had the best germicidal effect at 40 minutes. Disinfectant A had the germicidal effect decreased obviously at 60 minutes,while disinfectant B remained at a high level. Conclusion: Comparatively speaking, the disinfection effect of disinfectant B is slightly lower than disinfectant A, but the composition of disinfectant B is more stable and the germicidal maintenance time is longer than disinfectant A.
