用不同物质的量的β-FeOOH对蒙脱土(MMT)进行改性制备出一系列β-FeOOH-MMT(x),并将其与过氧化氢(H2O2)联用降解罗丹明B(RhB)。考察了RhB模拟废水脱色的影响因素,并研究了不同处理方法的协同效应。结果表明:在pH为5.2、β-FeOOH-MMT(3.5)用量为2 g/L、n(H2O2)∶n(Fe)=50∶1条件下搅拌10 min,对20 mg/L的RhB去除率可高达89.3%;对β-FeOOH-MMT(x)进行了拉曼光谱和扫描电镜表征。β-FeOOH-MMT(3.5)表现出丰富的孔结构;β-FeOOH-MMT(3.5)和H2O2对降解RhB模拟废水产生了协同效应,降解反应较为接近表观一级动力学,速率增强因子可达到29.32。

Montmorillonite was modified with different amounts of β-FeOOH to prepare a series of β-FeOOH-MMT(x),which were also linked with H2O2 to degrade the rhodamine B(RhB).The influence factors of RhB simulated wastewater deccolization were investigated and the synergistic effect of different treatment methods was investigated,and the experimental results showed that when pH=5.2,β-FeOOH-MMT(3.5) dosage of 2 g/L,n(H2O2)∶n(Fe)=50∶1,stir for 10 min,the 20 mg/L RhB removal rate could be as high as 89.3%.Raman spectroscopy and SEM were characterized for β-FeOOH-MMT(x).β-FeOOH-MMT(3.5) showed rich pore structure.β-FeOOH-MMT(3.5) and H2O2 had synergistic effect on degradation of RhB simulated wastewater.The degradation reaction was closer to the apparent first?order kinetics,and the rate enhancement factor could reach 29.32.
