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。
Oxidative hydrogels were prepared by impregnation method. The results showed that the release curves of different effective chlorine concentration aqueous electrolytes were similar. With the extension of the immersion time, the available chlorine concentration in the immersion liquid showed two peaks, corresponding to the rapid release of the oxidized electrolyzed water in the gel surface And oxidized electrolyzed water inside the gel to release. The higher the concentration of available chlorine in oxidized electrolyzed water, the more the mass concentration of available chlorine is released and the shorter the peak time is reached. On this basis, the bactericidal effect of the oxidized hydrogels was investigated. With the prolongation of the bactericidal time, the bactericidal effect of the oxidized hydrogels increased continuously. When the bactericidal time was 60 min, the bactericidal efficiency reached 79.76% (Ordinary hydrogel) sterilization efficiency of only 23.01%, an increase of nearly 4 times, indicating that the oxidation of electrolytic hydrogel has a good bactericidal effect, and significantly better than the no-load oxidized water hydrogels.
