Adsorption of Cu(II) from Aqueous Solution by Peanut Shell

Abstract:

Article Preview

A natural peanut shell was used as adsorbent for removal of Cu(Ⅱ) from aqueous solution. Optimum conditions for the elimination of Cu(Ⅱ) from aqueous solution were established by means of a batch adsorption technique. The applicability of the Langmuir and Freundlich adsorption isotherms for the present system was tested. The Langmuir adsorption capacity Qmax (mg/g) is 39.68 and the equilibrium constant b is 0.00776. The Freundlich adsorption capacity k is 0.978 and adsorption intensity n is 1.65. The goodness of fitness was obtained with the Langmuir and Freundlich adsorption isotherms from the equilibrium adsorption data.
