摘要
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 %。
potentiated alkaline glutaraldehyde solution is a glutaraldehyde compound disinfectant containing heptadecanol polyoxyethylene ether, sodium bicarbonate and sodium nitrite and has a pH value of 8 47 Its germicidal efficacy and corrosiveness were observed experimentally The results showed that this solution with a 1 hour contact time could kill 100% of spores of Bacillus subtilis var niger in suspension and it could destroy antigenicity of HBsAg on surface of stainless steel coupon in 20 min Its germicidal efficacy decreased with decreasing concentration of glutaraldehyde, presence of calf serum and absence of sodium nitrite in the compound disinfectant The glutaraldehyde content decreased by 1 05% after the disinfectant in binary packing was stored at 53～55℃ for 14 days and the glutaraldehyde content in the mixed solution decreased by 29 70% after storing at room temperature for 28 days This solution has no or esentially no corrosive effect on metals
