摘　　要：以硅藻土为载体、H2SO4为改性剂,Fe（NO3）3·9H2O为Fe源,采用浸渍蒸干法在不同Fe掺杂量的条件下制备载铁硅藻土非均相类Fenton反应催化剂,以酸性红B染料废水作为目标降解物,在不同催化条件下考察非均相类Fenton反应体系的性能。结果表明,非均相类Fenton反应体系有较宽的pH适应范围,当浸渍液浓度为0.5 mol/L时催化剂的活性最高,并且催化剂重复使用3次后酸性红B染料废水的色度去除率仍然高达78.26%。说明非均相类Fenton反应体系具有很好的降解性能。The Fe-containing diatomite heterogeneous Fenton-like reaction catalysts were prepared by evaporation impregnation liquid method under the condition of different Fe doping quantity with sulphuric acid modified diatomite as carrier and ferric nitrate as impregnation liquid. In dye wastewater, acid red B was degraded under different catalytic conditions to investigate the heterogeneous Fenton-like reaction performance. Catalysts would have the best catalytic effect when the soaking liquid concentration was 0.5 mol/L. After three times repeated use, the catalysts still had a capacity to remove 78.26% colourity from acid red B wastewater.
