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.
