    三氯异氰尿酸泡腾消毒片消毒性能的研究

    The Performance of Trichloro-isocyanuric Acid Effervescent Disinfectant Tablets

      摘要
    • 摘要:
      目的 研究三氯异氰尿酸泡腾消毒片的杀菌效果及消毒相关性能。
      方法 按《消毒技术规范》(2002年版)的方法, 对该泡腾消毒片的pH、有效氯含量、稳定性、杀菌试验、现场试验和模拟现场试验进行试验观察。
      结果 该泡腾消毒片有效氯含量为47.6%, 于54℃存放14 d后, 下降率为4.2%;试验溶液为500 mg/L, 对金黄色葡萄球菌、大肠杆菌分别作用10 min, 平均杀灭对数值均大于等于5.00;对物表消毒现场试验(对桌面自然菌作用10 min)平均杀灭对数值为1.56;对果蔬消毒模拟现场试验(对大肠杆菌作用30 min)和对食(饮)具消毒模拟现场试验(对大肠杆菌作用10 min)平均杀灭对数值均大于等于3.00;能量试验证明, 该泡腾消毒片对金黄色葡萄球菌杀灭最低合格浓度为500 mg/L。
      结论 该三氯异氰尿酸泡腾消毒片性能稳定, 有效氯浓度为500 mg/L, 对悬液内的细菌繁殖体和对人工染菌的果蔬、食(饮)具以及物体表面自然菌都有较强的杀灭作用。

       

      Abstract:
      Objectives To study the sterilizing and disinfecting performance of trichloro-isocyanuric acid effervescent disinfectant tablets.
      Methods Observing the pH value, available chlorine content, stability, bactericidal test, field test and stimulating field test of this effervescent disinfectant according to the "Technical Standard for Disinfection (2002)".
      Results The content of available chlorine of this effervescent disinfectant was 47.6%, which was decreased 4.2% after 14 d of storage at 54℃. With a concentration of 500 mg/L in the test liquid, the average killing logarithm for Staphylococcus aureus or Escherichia coli for 10 minutes was not less than 5.00; in a field test for killing natural bacteria on desktop for 10 minutes, the average killing logarithm value was 1.56; in stimulating field tests for killing Escherichia coli on fruits and vegetables and dinnerware disinfection for 30 minutes, the average killing logarithms were not less than 3.00. The results of an energy test showed that the minimum qualified concentration of this effervescent disinfectant for killing Staphylococcus aureus was 500 mg/L.
      Conclusions The efficacy of the effervescent disinfectant was stable, which played a strong role in killing bacteria in the liquid and on the surface of objects, dinnerware and fruits and vegetables.
