2 %强化碱性戊二醛溶液为含十七醇聚氧乙烯醚、碳酸氢钠、亚硝酸钠的戊二醛复方消毒剂 (pH8 4 7)。对其杀灭微生物效果及腐蚀性进行了试验观察。结果 ,该液对悬液中枯草杆菌黑色变种芽胞作用 1h ,杀灭率达 10 0 % ;作用 2 0min可使不锈钢片表面HBsAg抗原性破坏。其杀菌效果随戊二醛浓度减小、存在小牛血清、复方中不含亚硝酸钠而降低。其二元型原包装存放于 53～ 55℃下 14d ,戊二醛含量下降率为1 0 5% ;混合液存放室温下 2 8d者下降率达 2 9 70 %。该液对金属无或基本无腐蚀作用
The 2% fortified alkaline glutaraldehyde solution was glutaraldehyde compound disinfectant (pH 8.47) containing 17-mercaptoethanol, sodium bicarbonate and sodium nitrite. Its killing effect on microorganisms and corrosive experiments were observed. As a result, the liquid had a 1 h killing effect on the Bacillus subtilis black mutant spores in the suspension, and the killing rate reached 10%. Antioxidant HBsAg on the surface of the stainless steel plate was destroyed by the action of 20 min. The bactericidal effect decreased with the concentration of glutaraldehyde, the presence of calf serum, compound does not contain sodium nitrite decreased. The original dual-type packaging was stored at 53 ~ 55 ℃ for 14 days, the decreasing rate of glutaraldehyde content was 105%. The descending rate of the mixed solution stored at room temperature for 28 days was 2970%. The liquid has no or almost no corrosive effect on the metal
