摘要

  • 摘要: 将通过液相还原法制备的纳米铁/镍（Fe/Ni）颗粒承载于改性沸石表面制得负载型复合材料，纳米Fe/Ni在改性沸石表面具有良好的分散性。复合材料对2，4-二氯苯酚（2，4-DCP）的去除包括吸附和降解两个过程，脱氯降解是主要过程。实验结果表明，25℃时，0.6 g的复合材料对20 mg·L-1的2，4-DCP去除效果达到80%，在酸性条件下，复合材料的去除效果未见明显差异，碱性环境会影响2，4-DCP的去除效果。降解产物苯酚被吸附在材料表面，避免了对水环境的二次污染。
    Abstract: Iron/nickel (Fe/Ni) nanoparticles prepared by liquid-phase reduction were deposited onto the surface of modified zeolite to obtain a supported composite material. The Fe/Ni nanoparticles were well-dispersed on the surface of the modified zeolite. The removal path of 2,4-dichlorophenol (2,4-DCP) by the composite material includes adsorption and degradation,with the latter being the primary process. The experimental results show that nearly 80% of 2,4-DCP was removed under the following reaction conditions:initial 2,4-DCP concentration,20 mg·L-1;composite material dosage,6 g·L-1;and reaction temperature,25℃. The removal of 2,4-DCP by the composite material is significantly different under alkaline conditions but not acidic conditions. The degradation product of 2,4-DCP,phenol,was adsorbed on the surface of the material,avoiding secondary pollution of the water environment.
