Abstract

The applicability of banana peel as low cost adsorbent for the removal of cationic Malachite green (MG) and Methylene from aqueous solution has been studied. Banana peel, like other biomass has high content of carbohydrate and fiber with different functional groups such as hydroxyl (OH), carboxylic (COOH) and amines (NH2). This has been confirmed from the spectrum obtained from FTIR analysis. Batch adsorption studies were carried out to determine the effect of contact time and adsorption capacity of the biosorbent. Equilibrium was attained within 120 mins with equilibrium adsorption capacity (qe) of 107±1.3 mg/g and 120±2.7 mg/g for MG and MB cationic dyes respectively with a stirring rate of 200 rpm. Results from the effects of adsorbent dosage and initial dye concentrations have shown that 0.2 g of the adsorbent and 50 mg/g of the dye solutions were the optimum amounts for efficient removal of the dyes. The adsorption capacities were shown to be favored at high pH of the medium due to the high interactions between the surface of the adsorbent and the cationic dyes. From the economic point of view, regeneration and reusability of the adsorbent is a good indicator of its applicability as low-cost biosorbent for cationic dyes remediation in industrial wastewater
