中文摘要：

通过测定pH值、氧化还原电位(ORP)、溶解态铁离子和H2O2浓度等在Fenton反应中(初始Fe2+浓度为10~200mM)的变化,考察了葡萄糖、苯酚等对Fenton反应过程的影响,分析了生成的次生铁矿物组成.结果表明:初始Fe2+浓度≥50mM条件下的瞬时ORP和pH值随n(H2O2):n(Fe2+)摩尔比的增加呈先递增后快速降低的变化过程.初始葡萄糖和苯酚浓度为4.17mM、初始葡萄糖浓度为8.33mM时的H2O2基本耗尽时间分别约为15,10,2min;初始苯酚浓度为8.33mM、初始葡萄糖和苯酚浓度为16.66mM时的Fe2+浓度至60min末分别为7.40,27.40,58.83mM.初始pH值为3.3时Fenton反应形成的次生铁矿物经XRD分析初步鉴定为施氏矿物,其中添加葡萄糖或苯酚的Fenton反应生成的球形次生铁矿物其表面形成刺突.
