| 摘 要： | 实验室试验，过碳酸钠含量为０５％的溶液对大肠杆菌作用３０ｍｉｎ，其５０％溶液对金黄色葡萄球菌作用４５ｍｉｎ，杀灭率均达１００％。以其２００％溶液作用４ｈ，可将枯草杆菌黑色变种芽胞杀灭９９９８％，但不能将ＨＢｓＡｇ抗原性完全破坏。过碳酸钠固体避光于室温下保存１年，有效氧下降率为８６８％。其２００％溶液对所试金属基本无腐蚀性。

| Abstract: | In laboratory experiment, the killing rates of Escherichia coli exposed to 05% solution of sodium percarbonate for 30 min and Staphylococcus aureus exposed to its 50% solution for 45 min were 100%. Its 200% solution with a 4 hr contact time could kill 9998% of spores of Bacillus subtilis var. niger, but could not destroy completely the antigenicity of HBsAg. The available oxygen in solid sodium percarbonate decreased by 868% after storing at room temperature protected from light for 1 year. Its 200% solution was essentially not corrosive to the metals tested. |
