Neutralizer for glutaraldehyde disinfectant and preparation method thereof

The invention provides a neutralizer for glutaraldehyde disinfectants and a preparation method of the neutralizer. The neutralizer is prepared from the following raw material components in percentage by mass: 0.5 to 3 percent of glycine, 1 to 3 percent of polysorbate-80, 0.1 to 2 percent of sodium hydrogen sulfite, 0.5 to 3 percent of sodium thiosulfate and 0.5 to 3 percent of histidine. And the balance of purified water. The neutralizer is suitable for both single-component and compound glutaraldehyde disinfectants, can completely and efficiently neutralize the single-component or compound glutaraldehyde disinfectants, and can effectively avoid the influence of the disinfectant residue on the accuracy of the sterilization effect verification test. 本发明提出了针对戊二醛类消毒剂的中和剂及其制备方法，该中和剂包含以下质量百分比的原料组分：甘氨酸为0.5～3％，聚山梨酯-80为1～3％，亚硫酸氢钠为0.1～2％，硫代硫酸钠为0.5～3％、组氨酸为0.5～3％；余量为纯化水。该中和剂同时适用于单方和复方的戊二醛类消毒剂，对单方或复方的戊二醛类消毒剂均能起到完全、高效的中和作用，可有效避免消毒剂残留对杀菌效果验证试验准确性的影响。
