| 摘 要： | 目的探讨酸性氧化电位水(酸化水)中的成分过氧化氢(H2O2)和臭氧(O3)。方法测定有效氯浓度分别为31.91、43.24、51.40mg/L的酸化水中H2O2和O3的含量。并以与酸化水含相同Cl-浓度的氯化钠溶液作为待测液和在测酸化水中H2O2含量时使用丙二酸作为Cl2的掩蔽剂的待测液进行H2O2含量测定的对比实验。同时,考察了酸化水中Cl2与丙二酸在反应10、20、30min时对酸化水中O3含量测定结果的影响。结果随着酸化水中有效氯浓度的增加,H2O2含量呈下降趋势(均P<0.05)。当加入与酸化水含相同Cl-浓度的氯化钠溶液或过量的丙二酸后,酸化水中的H2O2含量与空白对照比较,差异均无统计学意义(P>0.05)。与空白对照比较,3种酸化水中O3含量的A值较高,差异均有统计学意义(P<0.05);且随着反应时间的延长和酸化水中有效氯浓度的增加,酸化水中O3浓度呈下降趋势。结论酸化水中可能含有低浓度的O3,不含H2O2,推测二者在酸化水杀菌作用中的贡献较小。

| Abstract: | Objective To investigate whether hydrogen peroxide (H2O2) and ozone (O3) present in electrolyzed oxidizing water (EOW). Methods The concentration of hydrogen peroxide and ozone in three kinds of electrolyzed oxidizing water (EOW) containing available chlorine 31.91,43.24 and 51.40 mg/L respectively were determined. The contrast experiments were also conducted. One was EOW replaced by sodium chloride solution,the Cl-concentration in which was the same as EOW. The other was adding malonic acid as the masking ... |
