  • 简介:以便执行decolorization,污泥蛋白质答案,黑暗棕色的结束到从激活的污泥的黑答案,面对氢受到60Co光线照耀过氧化物。UV/Visspectrophotometric方法被用来在着色法上调查H2O2的效果在光线照耀下面的污泥蛋白质答案的明显的动力学和率常数。另外,照耀剂量,起始的污泥蛋白质答案集中,和pH的效果在污泥蛋白质答案的decolorization效率上珍视被学习。结果证明污泥蛋白质答案的明显的动力学是的decolorization一阶的反应。答案decolorization百分比随照耀剂量的增加或起始的污泥蛋白质答案集中的减少增加了。pH价值的考试结果证明污泥蛋白质解决方案能更高效地比在酸媒介在碱的媒介被将脱色。而且,感觉评估和foamability分析显示在H2O2氧化下面的照耀的样品显示出更好感觉的分数和foamability。
