戊二醛作为常用的医用消毒剂具有灭菌效能高、杀菌力强的特点,尤其是质量分数为2.0%的戊二醛消毒液具有强大的杀灭细菌、病毒及芽孢的作用,被广泛应用于医院的医疗器械消毒工作中。但质量分数低于2.0%的戊二醛溶液,无论怎样延长杀菌时间,也不能取得可靠的杀灭细菌芽孢的效果[1],因此对戊二醛含量的测定就显得尤为重要。目前,卫生部2002年版《消毒技术规范》中规定了用羟胺法来测定
As a commonly used medical disinfectant, glutaraldehyde has the characteristics of high sterilization efficiency and strong bactericidal power. In particular, the glutaraldehyde disinfectant with a mass fraction of 2.0% has a strong effect of killing bacteria, viruses and spores and is widely used In the hospital medical equipment disinfection work. However, when the mass fraction of glutaraldehyde solution is lower than 2.0%, no effect of killing bacterial spores can be obtained no matter how long the sterilization time is prolonged [1]. Therefore, the determination of glutaraldehyde content is particularly important. At present, the Ministry of Health 2002 edition of “disinfection technical specifications” provides for the determination of hydroxylamine method
