摘　　要：制备质量分数分别为5%、10%和20%的纳米Fe/硅藻土改性材料,研究其脱硫效果,并与活性炭、硅藻土的吸附效果对比,研究纳米Fe/硅藻土改性材料对不同二氧化硫浓度的混合气体的脱硫效果。结果表明,纳米Fe/硅藻土改性材料的脱硫率可达95%以上,对低浓度二氧化硫的混合气体更适用。The nanoscale Fe/diatomite modified materials with 5%,10% and 20% respectively were prepared,and their desulfurization effects were studied and compared with the adsorption effects of activated carbon and diatomite.The desulfurization effect of nano Fe/diatom soil modified materials on mixed gas with different sulfur dioxide concentration was studied.The results show that the desulphurization rate of nano Fe/diatomite modified material can reach more than 95%,which is more suitable for the mixture of low concentration sulfur dioxide.
