Abstract

Industrialization and urbanization often lead to an increase in the discharge of toxic metals into the environment, which results in damage to ecosystems and human health. A recent focus on the removal of metal ions from solution is the use of agricultural and vegetable materials through adsorption. In the present study, the sportive potential of Morinda Citrifolia barks for Cu (II) ions has been investigated in a batch system. Equilibrium studies were performed to address various experimental parameters like pH, adsorbent dose and initial concentration for the removal of copper (II) ions. The adsorption data was described by Langmuir model. The values showed that acid treated Morinda Citrifolia has a better sorptive potential than base treated Morinda Citrifolia and both the adsorbents can be used for the economic treatment of wastewaters containing Copper (II) ions.
