Abstract
Bananas peel was used as an adsorbent to determine its feasibility for the removal of chromium (VI). Chromium heavy metal released into the environment has caused serious contamination of water and soils with significant environmental and occupational concerns. The removal of the Cr (VI) ions from aqueous solutions is investigated in this study using of banana peels as a low cost biosorbent material. Various parameters such as pH, temperature, contact time, initial metal concentration and adsorbent dosage were investigated to determine the biosorption performance. Equilibrium was attained within 60 minutes and maximum removal of 96% was achieved under the optimum conditions at pH 2. The adsorption phenomenon demonstrated here was monolayer represented by Langmuir isotherm with R2 value of 0.99 and the Langmuir constants k and qm was found to be 1,53 (L/mg) and 10,09 (mg/g). The adsorption system obeyed Pseudo second order kinetics with R2 value of 0.999.
