摘　　要：目的:为了准确、方便检测使用中消毒剂的污染菌。方法:配制一种广谱中和剂,并采用悬液法观察其对5种残留消毒剂的作用效果。结果:所配中和剂对0.5%过氧乙酸,84消毒液(1:200),2%戊二醛,75%乙醇,0.5%碘伏中和后菌落回收误差率分别是5.1%,3.5%,8.5%,6.3%,7.4%,均在规定范围内。结论:配制的中和剂能有效中和上述5种消毒剂对受试菌的残留作用,且中和剂及中和产物对受试菌的生长无影响。Objective：To detect the contaminated bacteria in the disinfectant more accurately and conveniently. Methods：A kind of broad - spectrum neutralizer was prepared and the effects on the 5 different kinds of disinfectant were studied by suspension test. Results ：0. 5% peroxyacetic acid , 84 disinfection solution （ 1 ： 200）, 2% glutaraldehyde, 75% ethanol and 0. 5% io- dophor were neutralized by the neutralizer we prepared and the recovery error rates of the bacterial colonies were 5.1%, 3.5 % , 8.5% ,6. 3% ,7.4% respectively. All the recovery error rates are within the acceptable limit. Conclusion：The neutralizer prepared can neutralize the remnant disinfectant effectively and both the neutralizer and the neutralization products have no effect on the growth of the bacteria tested.
