摘　　要：为减少染料对环境的污染,同时把生物废弃物变废为宝,以山竹果壳为原料制备了吸附剂。探究了山竹果壳吸附亚甲基蓝(MB)的性能。结果表明,MB的初始质量浓度为300.00 mg/L,MB体积为50 mL,山竹果壳投加量0.2 g, pH值10、温度35℃、吸附时间为120 min时,MB的最大吸附量为145.89 mg/g。应用准一级动力学方程、准二级动力学方程、Weber-Morris颗粒扩散方程和Boyd模型拟合了山竹果壳粉吸附MB的动力学过程,利用Freundlich和Langmuir方程模拟其热力学行为。结果表明山竹果壳吸附MB的过程适合于准二级动力学、Langmuir模型。To mitigate the environmental impact of dye pollution and convert biological waste into valuable resources,an adsorbent was developed from mangosteen fruit shells.The study focused on the ability of these shells to adsorb methylene blue(MB).Findings indicated that at an initial MB concentration of 300.00 mg/L,MB volume of 50 mL,with a dosage of 0.2 g of mangosteen shell,a pH value of 10,a temperature set at 35℃,and an adsorption duration of 120 minutes,the maximum adsorption capacity reached 145.89 mg/g.The kinetics for MB adsorption by mangosteen fruit shell powder were analyzed using quasi-first-order and quasi-second-order kinetic models,as well as the Weber-Morris particle diffusion model and Boyd model.Additionally,thermodynamic simulations for MB adsorption were conducted using Freundlich and Langmuir equations.Results demonstrated that the adsorption behavior followed quasi-second-order kinetics and conformed to the Langmuir isotherm model effectively.
