以塑料为原料、改性煤矸石为模板，在管式炉中用KOH进行活化制备多孔碳材料（PCM）。利用SEM、FT-IR、XRD和氮气吸-脱附对样品的形貌、成分及孔结构进行表征，并以亚甲基蓝（MB）为模拟污染物研究碳材料的吸附性能。结果表明，10 mg PCM在240 min内可使初始质量浓度为100 mg/L的MB几乎完全吸附，吸附量达498.35 mg/g，降解率达99.67%。对吸附过程进行拟合后得出，准二级动力学模型可以更好地描述该吸附过程，吸附等温模型符合Langmuir吸附等温模型。

Porous carbon material (PCM) is prepared by using plastics as raw material,modified gangue as template and performing activation with KOH in a tube furnace.The morphology,composition and pore structure of PCM samples are characterized by SEM,FT-IR,XRD and nitrogen adsorption-desorption,and the absorptive performance is studied through using methylene blue as simulated pollutant.It is shown that the prepared PCM has a spheroidal structure,and the specific surface area and total pore volume of the activated material are 535.210 7 m²·g^-1 and 0.367 5 cm³·g^-1 respectively.The adsorption properties of carbon materials are studied by using methylene blue (MB) as a simulated pollutant.The results show that 10 mg of PCM can almost completely absorb MB with an initial concentration of 100 mg·L^-1 in 240 min,with an adsorption capacity of 498.35 mg·g^-1 and a degradation rate of 99.67%.After fitting the adsorption process,the quasi-secondary kinetic model can better describe the adsorption process,and the adsorption isothermal model is more in line with Langmuir adsorption isotherm model.
