Abstract

Biosorption of Copper II Ions by Eclipta Alba Leaf Powder from Aqueous Solutions

Highlights

  • Industrial wastewater treatment for the removal of pollutants such as heavy metal ions remains a worldwide challenge

  • Adsorption is an alternative technology in which increased amount of study has been focused because of cost effectiveness; local availability & technical feasibility for the removal of heavy metal ions form the wastewater [10]

  • The aim of the present study is to investigate the bio sorption of copper (II) on Eclipta Alba leaves powder

Summary

Introduction

Industrial wastewater treatment for the removal of pollutants such as heavy metal ions remains a worldwide challenge. Removal of metal ions from wastewater in an effective manner has become an important issue. Precipitation, ion-exchange, flocculation, adsorption, electro-chemical processes, electrodialysis, nano-filtration and reverse osmosis are commonly applied for the treatment of wastewater [8]. These methods are either inefficient or expensive when heavy metals exist in low concentrations [9]. Adsorption is an alternative technology in which increased amount of study has been focused because of cost effectiveness; local availability & technical feasibility for the removal of heavy metal ions form the wastewater [10]. Bio sorption has been suggested as being cheaper and more effective than chemical or physical
