摘要:

为了考察过硫酸氢钾复合物粉的质量特性，通过水中溶解度、水中有效氯稳定性、金属腐蚀性、局部刺激性以及对目标病原微生物的杀灭效果等试验，对过硫酸氢钾复合物粉进行质量研究。结果表明，过硫酸氢钾复合物粉在水中的最大溶解度可达到60.0 g/L，且其溶液有效氯的稳定性可达10天左右。过硫酸氢钾复合物粉溶液对不锈钢无腐蚀作用，但是对铝、铜和碳钢等金属均具有不同程度的腐蚀作用。经验证，过硫酸氢钾复合物粉溶液对皮肤和眼睛等无明显的刺激性，但对病原微生物具有一定的杀灭效果：1.0 g/L的过硫酸氢钾复合物粉溶液5 min内可有效杀灭大肠杆菌和金黄色葡萄球菌；10 min内可有效杀灭沙门氏菌和链球菌。2.5 g/L的过硫酸氢钾复合物粉溶液在作用5 min后可有效灭活非洲猪瘟病毒。上述试验结果均表明，过硫酸氢钾复合物粉是一种可有效杀灭病原微生物的新型消毒剂。

Abstract:

In order to investigate the quality characteristics of potassium peroxymonosulphate powder, the solubility in water, the stability of available chlorine in water, the corrosive action on metals, the local irritation and the disinfection effect on target pathogenic microorganisms, were studied. Results showed that the maximum solubility in water was 60.0 g/L and the stability of available chlorine in water lasted about 10 days. The potassium peroxymonosulphate solution had no corrosive effect on stainless steel, but had different degrees of corrosive effects on aluminum, copper and carbon steel. Potassium peroxymonosulphate solution had no obvious irritation to rabbit’s skin and eyes, but had great disinfection effect on target pathogenic microorganisms. Potassium peroxymonosulphate solution at the concentration of 1.0 g/L could kill Escherichia coli and Staphylococcus aureus effectively within 5 minutes, and it could kill Salmonella and Streptococcus effectively within 10 minutes. Potassium peroxymonosulphate solution at the concentration of 2.5 g/L could kill African swine fever virus in 5 minutes. The above results demonstrated that potassium peroxymonosulphate powder was a new type of disinfectant, which was safe, non- irritating and had great disinfection effect on target pathogenic microorganisms.
