采用载体定量杀菌试验，观察紫外线与戊二醛协同杀菌效果。结果，以辐照度值为９５μＷ／ｃｍ２的紫外线与 １０％酸性成二醛协同，对玻璃片与滤纸片上金黄色葡萄球菌、大肠杆菌作用 ０．５ ｍｉｎ，对两片上枯草杆菌黑色变种芽胞作用 １０ ｍｉｎ，杀灭率均≥９９．９％；两因子单独作用则均达不到。 Quantitative bactericidal test using a carrier to observe the synergistic bactericidal effect of UV and glutaraldehyde. As a result, UV irradiation with an irradiance value of 95 μW / cm2 was synergized with 10% of acidity dialdehyde to act on Staphylococcus aureus and Escherichia coli on the glass plate and the filter paper for 0.5 min, and to effect the Bacillus subtilis var. 10 min, killing rate were ≥ 99.9%; two factors were alone can not reach.
