Adsorption of Copper (II) ions from SyntheticWaste Water By Teak Leaves

Studies on a batch adsorption system using Teak Leaves Powder as adsorbent were carried out to remove copper from waste water. The aim of the present investigation is to study the potential of teak leaves for copper removal and optimize the parameters like contact time, pH and the temperature. Optimum contact time found to be 60 minute as after that desorption also become dominant. As adsorbent dose increases, % removal increases as surface area increases for adsorption.The optimum dose was 2 g/l. Maximum % removal was at 55 0 C. The equilibrium adsorption data were fitted to Langmuir and Freundlich adsorption isotherm models and model parameters were evaluated. We can say both models were suited to the experimental equilibrium data for teak leaves because value of R 2 was found to be 0.993 and 0.995 respectively. The results show that Teak Leaves Powder has scope for modification, to use it as low cost adsorbent for adsorption of Cu (II) from aqueous solution.
