以铁精粉、煤粉与造纸污泥为原料，采用直接还原法制备多孔铁炭微电解填料，对其进行了表征，考察了铁炭填料对Pb2+的吸附特性，并与活性炭的吸附性能作了比较. 结果表明，铁炭填料孔隙率为32.3%~52.9%，金属铁含量达50%以上，铁炭质量比可调. 吸附Pb2+的最佳铁炭质量比为6.8:1, pH=3时铁炭填料对Pb2+的吸附量最大；吸附速度快，符合准二级吸附动力学模型，等温吸附过程可用Langmuir等温吸附模型描述；铁炭填料和活性炭对Pb2+的最大吸附量分别为112.36和27.94 mg/g，铁炭填料吸附Pb2+的性能远高于活性炭.

The porous Fe/C micro-electrolysis filter was prepared from the iron ore concentrate, coal and papermaking sludge via a direct reduction method. The Fe/C filter was characterized. The adsorptive properties of Pb2+ in aqueous solution were tested by using Fe/C filter and activated carbon, respectively. The results showed that the Fe/C filter had the porosity of 32.3%~52.9%, metallic iron content of over 50% and adjustable Fe/C mass ratio. The optimized mass ratio of Fe to C was 6.8, and the largest adsorption capacity of Pb2+ was obtained at pH=3. The Pb2+ adsorption process with both the Fe/C filter and activated carbon fitted well with a pseudo-second order kinetic model. Langmuir isotherm equation could be used to evaluate the Pb2+ adsorptive capacity. The maximal adsorption capacity of Pb2+ was 112.36 and 27.94 mg/g for the Fe/C filter and activated carbon, respectively, showing the much higher adsorption capacity of the Fe/C filter.
