Elimination of Cu (II) Cations from Water Media Using Clean Adsorbent as Application of Green Chemistry: Acacia Tortilis Seeds

M. A. Ackacha and S. A. Meftah

Abstract—Acacia tortilis seeds were treated with natural lemon juice and used as clean adsorbent for removal of Cu (II) cations from water environment. Adsorption experiments were preformed by studying some parameters include initial pH, contact temperature, contact time and initial Cu (II) concentration, on adsorption of Cu (II) cations onto Acacia tortilis seeds. The optimum conditions were obtained 3, 50 oC, 90 minutes, 600 mg/l as initial pH, contact temperature, contact time and initial Cu (II) concentration, respectively. Adsorption kinetic models include Lagergren first-order, pseudo-second-order and intra-particle diffusion were applied in order to investigate the adsorption mechanism. Two different isotherm models includ Langmuir and Freundlich were used to investigate the adsorption process. Thermodynamic parameters, such as ΔGº, ΔHº and ΔSº, were calculated.

Index Terms—Acacia tortilis, adsorption, Lagergren first-order, pseudo second order.
