Removal of Zinc Metal Ions from Electroplating Industrial Waste Water by Using Bio-Sorbent

The adsorption of Zinc from electroplating industrial effluent by banana peel powder was investigated. The influence of pH of sample, adsorbent dosage, temperature and contact time were evaluated on the bio-sorption studies. The present study aims to investigate efficiency of banana peel as an absorbent for removal of zinc from effluent by batch experiments. In order to investigate the bio-sorption isotherms, two equilibrium models, Langmuir and Freundlich isotherms were analyzed. This study focuses on optimization of contact time, pH, temperature and adsorbent dosage of banana peel for removal of heavy metals from effluent of electroplating industry.
