芬顿试剂处理废水相关问题芬顿试剂处理高有机物时,加入硫酸亚铁和双氧水的测序是什么?加入的量有什么比例吗?COD 1万左右

你在加双氧水的时候废水ph是多少,反应完以后ph调到了多少,然后你取处理废水水样是1ml吗?还有30%的芬顿处理你这个cod的废水,低于5ml效果是不佳的,理论的cod：H2O2=1:2.13,说实话,你这个cod用芬顿,简直就是土豪,哈哈

Of fenton reagent processing laboratory simulation studies were conducted to investigate the treatment effect of wastewater containing phenol,mainly examines the variables of additive amount of hydrogen peroxide and ferrous sulfate dosing quantity,pH value,and under different conditions,such as adsorption time fenton reagent effect on the treatment effect of wastewater containing phenol.Comprehensive fenton reagent proportion and reaction conditions are best,examining the effects of different concentrations of phenol wastewater treatment.Results show that in the normal temperature condition,the 1 g/L of the phenol solution on the best processing condition that hydrogen peroxide (analysis of 30 0) the additive amount to 20 ml,seven water ferrous sulfate dosing quantity is 1390 mg,pH value of 3,the reaction time is 25 m in,the phenol removal rate is about 96.5 3 under the condition of different concentrations of phenol solution,joined by more than the best proportion of fenton reagent,the result shows that the phenol concentration between 0.1 to 6.0,the phenol removal rate kept in 90 .

芬顿试剂：是以亚铁离子(Fe2+)为催化剂用过氧化氢(H2O2)进行化学氧化的废水处理方法.由亚铁离子与过氧化氢组成的体系,也称芬顿试剂,它能生成强氧化性的羟基自由基,在水溶液中与难降解有机物生成有机自由基使之结构破...

把FeSO4溶于水,用H2SO4调节PH至所需,再加过氧化氢溶液.因为芬顿试剂pH只是一个大致范围,不必准确.即使加过氧化氢溶液后溶液体积扩大一倍,PH也大约增加0.3.

过氧化氢(H2O2)与二价铁离子Fe^2+的混合溶液具有强氧化性,可以将当时很多已知的有机化合物如羧酸、醇、酯类氧化为无机态,氧化效果十分明显.此后半个多世纪中,人们对这种氧化性试剂的应用报道不多,关键是它的氧化性极强,一般的有机物可完全被氧化为无机态.

芬顿试剂是由过氧化氢和硫酸亚铁盐配成的氧化试剂.过氧化氢和Fe(2+)(上标下同)反应形成HO*游离基:
Fe(2+)+HO:OH---→Fe(3+)+OH(-)+HO*
为芳香化合物的羟基化试剂：
Ar---------→(H2O2+FeSO4)----→ArOH
可作醇等的氧化试剂、可用于醛糖的降级,生成少一个碳原子的醛糖,此法称为鲁夫-芬顿醛糖降级法.

芬顿试剂产生羟基自由基：
Fe2+十H+十H2O2=Fe3+十H2O十﹡OH
羟基自由基氧化性极强.
6﹡OH+CH3OH=CO2↑+5H2O

芬顿试剂中的氧化剂是H2O2,而H2O2的氧化性比MnO4-强：
H2O2 + 2e + 2H+ = 2H2O,E=1.776V
MnO4- + 5e + 8H+ = Mn2+ + 4H2O,E=1.57V
