Abstract :

A basic investigation on the removal of Cr (VI) and Cu (II) ions from metal solution using crosslinked chitosan–g–acrylonitrile copolymer was conducted in a batch adsorption system, for finding the effect of various parameters such as initial concentration of the metal solution, contact time, adsorbent dose and pH. The results show the adsorption efficiency of the prepared novel adsorbent for the heavy metal treatment. A pH 5.0 was found to be an optimum pH for both Cr (VI) and Cu (II) adsorption. The adsorption data have been explained in terms of Langmuir and was found to be fit well with the Langmuir isotherm model. The maximum adsorption capacities for Cu (II) and Cr (VI) ions were 230.79 mg/g and 122.83 mg/g, respectively. From the above results it was concluded that under optimum conditions, the chitosan grafted poly AN was found as an effective adsorbent for copper.
