: Adsorption of Cu (II) metal ions into non-conventionalphaseolusaureusadsorbents developed from seed husk of phaseolusaureus was investigated in batch adsorption technique. The aim of the present investigation is to study the potential of GGSH for Cu(II) ion adsorption and optimize the parameters like contact time, adsorbent dosage, initial metal ion concentration, initial pH and temperature of solution were varied in order to evaluate their influence on the adsorption process. The results obtained indicate that the adsorption of Cu(II) metal ion on GGSH is better at higher metal ion concentration and higher adsorbent dose. The maximum adsorption capacity was found to be 400.00 mg/g which was obtained at 100 mg/L metal ion concentration and 0.5 gm of GGSH dose. pH 5.10 was chosen as the optimum pH and better adsorption occurred at lower solution temperature. Theequilibrium adsorption data was fitted to Langmuir adsorption model and model parameters were evaluated. We can say Langmuir adsorption model was suited to the experimental equilibrium data for GGSH because value of R2 was found to be 0.999. The result shows that GGSH powder has scope for modification to use as low cost adsorbent for adsorption of Cu(II) from aqueous solution.
