Abstract

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.
