摘　　要：利用浸渍法制备了氧化电解水凝胶。结果表明,不同有效氯质量浓度氧化电解水凝胶释放曲线类似,随着浸渍时间的延长,浸渍液中有效氯质量浓度变化呈现2个峰值,分别对应着凝胶表层中氧化电解水快速释放出和凝胶内部的氧化电解水释放。氧化电解水有效氯质量浓度越高,释放出来有效氯的质量浓度越多,达到峰值时间越短。在此基础上,考察了氧化电解水凝胶的杀菌作用,随着杀菌时间的延长,氧化电解水凝胶的杀菌效果不断提高,当杀菌时间为60 min,杀菌效率达到79.76%;而对照组(普通水凝胶)的杀菌效率仅为23.01%,提高了近4倍,说明氧化电解水凝胶具有较好的杀菌作用,且明显优于无负载氧化电解水的水凝胶。The electrolyzed oxidizing water hydrogel（ EOW hydrogel） is prepared by impregnation method. The results show that the release curve of the EOW hydrogel with different active chlorine content（ ACC） is similar. With the extension of the soaking time,the ACC of the dipping solution shows two peaks,which are corresponding to the fast release of EOW in the surface of the gel and the release of EOW from the inner of the gel. The higher ACC in the EOW,the more chlorine content is released and the shorter the peak time reaches. On the basis of the study,the germicidal efficacy of the EOW hydrogel is investigated. It has a good bactericidal effect in the continuous sterilization,which is better than the non-loaded EOW hydrogel. With the prolonging of the sterilization time,the sterilization effect of the EOW hydrogel is increasing. When the sterilization time is 60 minutes,the sterilization efficiency reaches 79. 76%,while the control group（ conventional hydrogel） of the sterilization efficiency is only 23. 01%. It indicates that the EOW hydrogel has a good bactericidal effect.
