Abstract

The occurrence of heavy metals in water constitute a major threat to both humans and aquatic animals. The current research work investigated the adsorptive behavior of a natural clay obtained from Goronyo Local Government, Sokoto state, Nigeria for Pb(II) and Cd(II) ions removal from aqueous solution. The clay sample was characterized using different techniques (X-ray fluorescence, X-ray diffraction, and Fourier transform infrared spectroscopy). Batch adsorption method was employed at room temperature to investigate the amount of metal ion adsorbed per gram of clay as a function of solution pH, contact time, adsorbent dosage and metal ion concentration. Optimum adsorption was attained at solution pH of 5.5 and 6 for Pb(II) and Cd(II) ions, respectively, contact time of 60 min, adsorbent dosage of 0.5 g/50 mL and metal ion concentration of 50 mg/L. Kinetic analysis revealed that the adsorption conform to pseudo-second order kinetic model. Among the different isotherms tested, the Freundlich and Langmuir isotherms gave the best fit, illustrating that the interaction was predominantly chemical in nature but the adsorption sites were heterogeneous. The maximum adsorption amount per gram of the clay adsorbent was found to be 49.72 and 31.63 mg/g for Pb(II) and Cd (II) ions, respectively. These results suggest that GN clay can be efficiently utilized as a low-cost adsorbent for metal ions removal from aqueous systems.

AB  - The occurrence of heavy metals in water constitute a major threat to both humans and aquatic animals. The current research work investigated the adsorptive behavior of a natural clay obtained from Goronyo Local Government, Sokoto state, Nigeria for Pb(II) and Cd(II) ions removal from aqueous solution. The clay sample was characterized using different techniques (X-ray fluorescence, X-ray diffraction, and Fourier transform infrared spectroscopy). Batch adsorption method was employed at room temperature to investigate the amount of metal ion adsorbed per gram of clay as a function of solution pH, contact time, adsorbent dosage and metal ion concentration. Optimum adsorption was attained at solution pH of 5.5 and 6 for Pb(II) and Cd(II) ions, respectively, contact time of 60 min, adsorbent dosage of 0.5 g/50 mL and metal ion concentration of 50 mg/L. Kinetic analysis revealed that the adsorption conform to pseudo-second order kinetic model. Among the different isotherms tested, the Freundlich and Langmuir isotherms gave the best fit, illustrating that the interaction was predominantly chemical in nature but the adsorption sites were heterogeneous. The maximum adsorption amount per gram of the clay adsorbent was found to be 49.72 and 31.63 mg/g for Pb(II) and Cd (II) ions, respectively. These results suggest that GN clay can be efficiently utilized as a low-cost adsorbent for metal ions removal from aqueous systems.
