The aim of this study was the production of high surface area activated carbon (AC) under optimized synthesis conditions from Mangosteen Peels (MP) waste using a single step ZnCl₂ activation process. The influence of the various activation parameters such as impregnation ratio, impregnation time, carbonization time, and carbonization temperature on surface area and pore characteristics of synthesized ACs was investigated. The AC prepared under optimized conditions showed BET surface area, average pore diameter, and total pore volume of 1621.8 m²/g, 4.4 nm, and 1.805 cm³/g, respectively. The optimized synthesis conditions were as follows: 1:4 impregnation ratio, 600 °C calcination temperature, and 30 min calcination time. The characteristics of the optimized AC were analyzed using nitrogen adsorption-desorption isotherm, scanning electron microscopy, pore structural analysis, Fourier transformed infrared spectroscopy and X-Ray diffraction analysis. The adsorption capacity of activated carbon prepared under optimized conditions for methylene blue was 1193 mg/g. Equilibrium data was best fitted to the Langmuir isotherm, while adsorption kinetic was favorably described by the pseudo-second-order kinetic model. The findings reveal the feasibility of mangosteen peel waste to be used as a potential and cheap precursor for the preparation of high surface area mesoporous AC.

这项研究的目的是使用单步ZnCl ₂活化工艺在山竹果皮（MP）废料的优化合成条件下生产高表面积活性炭（AC）。研究了浸渍比，浸渍时间，碳化时间，碳化温度等各种活化参数对合成ACs的表面积和孔特性的影响。在优化条件下制备的AC的BET表面积，平均孔径和总孔体积为1621.8 m ² /g、4.4 nm和1.805 cm ³/ g。优化的合成条件如下：浸渍比为1：4，煅烧温度为600°C，煅烧时间为30分钟。使用氮气吸附-解吸等温线，扫描电子显微镜，孔结构分析，傅立叶变换红外光谱和X射线衍射分析对优化后的AC的特性进行了分析。在优化条件下制备的活性炭对亚甲基蓝的吸附容量为1193 mg / g。平衡数据最适合Langmuir等温线，而吸附动力学由拟二级动力学模型很好地描述。这些发现揭示了山竹果皮废料被用作制备高表面积介孔AC的潜在且廉价的前体的可行性。
