摘要
提高Fenton试剂在废水处理中的氧化功效,关键在于提高体系中.OH的生成率。本文采用邻二氮菲-Fe(Ⅱ)光度法间接测定.OH,研究了Fenton试剂中.OH表观生成率的主要影响因素:Fe2+的浓度、H2O2的浓度、pH值及反应时间,并结合实际应用,考察了工业废水中常见无机离子对.OH生成率的影响,从而为Fenton试剂法更好地应用于废水处理提供了技术依据。
The key to enhance the efficiency of oxidation of Fenton reagent in wastewater treatment is to improve the productivity of hydroxyl radical in the system. In this paper, hydroxyl radicals was indirectly determined by Fe （phen）3^2＋ method, and the leading factors influencing the apparent productivity of hydroxyl radicals in Fenton＇s reagent such as the concentration of ferrous iron （Fe^2＋） , the amounts of H2O2 ,pH and reaction time were studied. In the actual application ,the influence of the inorganic ion on the productivity of hydroxyl radicals was investigated in the industrial wastewater. The useful technique parameters for Fenton reagent treating wastewater were offered.
