2009年安徽省高考试卷28题以Fenton法处理含难降解有机物的工业废水为背景,考查了化学反应速率的计算、影响因素等相关知识,更注重对学生读图能力和分析问题能力的考查。在此题基础上,笔者查阅相关资料,就Fenton法作简单介绍,并设计相关练习。一、Fenton法简介1894年,英国科学家H.J.H.Fenton发现将H_2O_2和Fe~(2+)混合可以氧化多种有机化合物,后人就将H_2O_2/Fe~(2+)的体系(通常用亚铁盐和过氧化氢组合)称为Fenton试剂。现在Fenton试剂广泛用于处理难降解的、有
In 2009 Anhui province college entrance examination paper 28 questions Fenton method for treatment of industrial wastewater containing refractory organic matter as the background, examines the calculation of chemical reaction rates, influencing factors and other related knowledge, pay more attention to students’ reading ability and ability to analyze problems. On this basis, the author access to relevant information on the Fenton method for a brief introduction, and design related exercises. First, the Fenton method profile In 1894, the British scientists HJHFenton found that H_2O_2 and Fe ~ (2+) can be mixed to oxidize a variety of organic compounds, descendants will H_2O_2 / Fe ~ (2+) system (usually with ferrous salt And hydrogen peroxide) is called Fenton’s reagent. Fenton reagents are now widely used to treat refractory ones
