Abstract The paper addresses an exploration of the removal efficiency of banana peel ftrip(BP) towards copper and zinc ions from water and to optimize the factors involved in this adsorption process. In this sense, process optimization, kinetics, and equilibrium studies were performed in a batch process. The kinetics shows that the equilibrium reached in 60 minutes and the adsorption is favored above pH 5. The BP was firstly characterized by proximate analysis, FTIR, BET surface area, and SEM. The highest adsorption capacity for Langmuir isotherm for Cu(II) and Zn(II) onto BP was observed to be 61.728 mg/g and 55.56 mg/g respectively. Finally, the regeneration of BP was also studied up to 5 cycles. Thus, BP showed excellent adsorption characteristics during the uptake of Cu(II) and Zn(II) from wastewater effluent and can be used as low-cost agricultural waste biomass as an adsorbent.

Cu(II) 和 Zn(II) 在香蕉皮上的吸附/解吸、动力学和平衡研究

摘要 本文探讨了香蕉皮 ftrip(BP) 对水中铜和锌离子的去除效率，并优化了该吸附过程中涉及的因素。从这个意义上说，过程优化、动力学和平衡研究是在批处理过程中进行的。动力学表明，在 60 分钟内达到平衡，并且在 pH 5 以上时有利于吸附。首先通过近似分析、FTIR、BET 表面积和 SEM 对 BP 进行表征。观察到对铜（II）和锌（II）的 Langmuir 等温线在 BP 上的最高吸附容量分别为 61.728 mg/g 和 55.56 mg/g。最后，BP 的再生也进行了多达 5 个循环的研究。因此，
