目的比较国内外不同企业生产的五种邻苯二甲醛消毒剂产品对细菌芽孢的杀灭效果,以了解该消毒剂产品实际状况。方法采用载体定量杀菌试验进行实验室观察。结果五种邻苯二甲醛消毒剂产品含量在5 000~6 000 mg/L范围,pH值范围在7.40~8.75。三种国产邻苯二甲醛消毒剂中,一种能在20 min内对载体上枯草杆菌黑色变种芽孢杀灭对数值达到3.0以上,另两种需要作用60 min。两种进口邻苯二甲醛消毒剂作用60 min,对载体上枯草杆菌黑色变种芽孢杀灭对数值均小于3.0。结论目前市售邻苯二甲醛消毒剂对细菌芽孢杀灭效果存在明显差异,应加强市场监督监测力度。
Objective To compare the killing effect of five kinds of o-phthalaldehyde disinfectant products produced by different enterprises at home and abroad on bacterial spore in order to understand the actual situation of the disinfectant products. Methods Quantitative bactericidal test using a carrier for laboratory observation. Results The content of five phthalaldehyde disinfectants was in the range of 5000-6000 mg / L and the pH was in the range of 7.40-8.75. Among the three kinds of domestic ortho-phthalaldehyde disinfectants, one can kill the bacillus subtilis black spores on the carrier to a logarithmic value of 3.0 or more within 20 min, and the other two require 60 min. Two kinds of imported phthalaldehyde disinfectant effect 60 min, on the carrier Bacillus subtilis black spores kill logarithm values are less than 3.0. Conclusion Currently, there is a significant difference in the killing effect of the phthalic aldehyde disinfectants on bacterial spores, and market supervision and monitoring should be strengthened.
