A simple synthesis route has been developed to prepare pitch resin, which has been as carbon precursor to fabricate graphitic mesoporous carbon by a nanocasting process, and directly incorporating iron metal nitrates species as the magnetic particle precursors infiltrated into the mesoporous framework via two different approaches. The results of nitrogen adsorption-desorption showed a decrease in specific surface area and total volume with magnetic treatment. Comparison between the AB1 dye elimination with two magnetic nanocomposites was investigated. Experimental results showed that the adsorption capacities of the graphitic mesoporous carbons under the impregnation treatment (GMC-I) and the thermal treatment (GMC-II) modification nanoparticles for AB 1 dye were calculated to be 361.7 mg g⁻¹ and 304.5 mg g⁻¹, respectively. The results exhibited that the obtained magnetic mesoporous graphitic carbon nanocomposites can be used as efficient and recycled adsorbents for the removal of bulky dyes from any real sample. In additions, the data of kinetic was well fitted by pseudo second-order model, and the equilibrium adsorption isotherm data of dye onto the two magnetic GMC fitted by Langmuir isotherm model. The calculated thermodynamic parameters (ΔG, ΔH and ΔS) showed that the AB 1 dye adsorption onto the two nanocomposites was feasible, spontaneous and endothermic.

已开发出一种简单的合成路线来制备沥青树脂，该树脂已作为碳前体通过纳米浇铸工艺制造石墨中孔碳，并通过两种不同方法直接掺入了铁金属硝酸盐类作为渗透到中孔骨架中的磁性颗粒前体。氮吸附-解吸的结果显示，通过磁处理，比表面积和总体积减小。研究了用两种磁性纳米复合材料消除AB1染料的比较。实验结果表明，浸渍处理（GMC-I）和热处理（GMC-II）改性纳米粒子对石墨中孔碳对AB 1染料的吸附能力分别为361.7 mg g ^-1和304.5 mg g^-1。结果表明，所获得的磁性介孔石墨碳纳米复合材料可用作有效的和循环利用的吸附剂，用于从任何真实样品中去除大体积的染料。另外，动力学数据可以通过拟二阶模型很好地拟合，染料的平衡吸附等温线数据可以通过Langmuir等温模型拟合到两个磁性GMC上。计算得出的热力学参数（ΔG，ΔH和ΔS）表明，AB 1染料吸附在两个纳米复合材料上是可行的，自发的和吸热的。
