• W2331899023 abstract "Aims: To compare the efficiency of Sorghum Hull of two different particle sizes, different concentrations modified with mercaptoacetic acid and the effect of each on the heavy metal removal to obtain optimum conditions for sorption process. Study Design: The concentrations of the metal ions were monitored using Atomic Absorption Spectrophotometer (AAS). Place and Duration of Study: This study was carried out at the Industrial Chemistry laboratory, Department of Pure and Industrial Chemistry, University of Port Harcourt between February and August 2013. Original Research Article Imaga et al.; IRJPAC, 5(4): 318-330, 2015; Article no.IRJPAC.2015.025 319 Methodology: The Sorghum Hulls (SH) (Sorghum bicolor) obtained from a Brewery, were washed and air dried, crushed to smaller particles and sieved to obtain particle sizes of 106 μm and 250 μm. They were activated by soaking in excess of 0.3M HNO3 solution for 24 h, filtered through a Whatman No.41 filter paper, rinsed with deionised water and air dried for 24 h. The air-dried activated sorghum hulls were divided into three parts, one part was left unmodified and the other two parts were modified by 0.5M and 1.0M mercaptoacetic acid (HSCH2COOH). Equilibrium sorption of Ni (II), Cu (II) and Zn (II) were carried out for each adsorbent (106 μm and 250 μm) at pH of 6.0 and temperature of 28°C to find the effects of initial concentration on the sorption process by preparing stock solutions of 1000 mg/L of Cu (II), Ni (II) and Zn (II) ions from CuSO4, Ni(C2H3O2)2, and ZnSO4 respectively. Working concentrations of 10, 20,30,40,50 mg/L were obtained by serial dilutions. The concentrations of these solutions were confirmed using Atomic Absorption Spectrophotometer (AAS). The difference in the metal ion concentration of the solutions before and after sorption gave the amount adsorbed by each adsorbent. Results: Sorption efficiency followed the trend Cu 2+ >Ni 2+ >Zn 2+ and Ni 2+ >Cu 2+ >Zn 2+ for 106μm and 250μm, respectively. This was influenced by factors such as ionic radii, ionic charge, hydration energy, initial metal ion concentration, contact time, adsorbate pH and extent of acid modification. Sorption capacity followed the sequence: 1.0MSH>0.5MSH>USH. Equilibrium sorption of the three metals on the adsorbents using coefficient of determination (R) showed that sorption of Zn on 250μm size and sorption of Ni 2+ on 106μm size followed Langmuir isotherm; sorption of Zn 2+ on 106μm mesh and sorption of Cu on 250μm size by Freundlich isotherm and sorption of Cu on 106μm size and sorption of Ni 2+ on 250μm mesh by Temkin isotherm. Sorption on 1.0MSH gave the highest value of constants: (qmax = 121.814 mg/l, KF = 1.5281 mg/l and bT = 0.245 kJ/mol) and (qmax = 148.932 mg/l, KF = 1.7246 mg/l and bT = 0.262 kJ/mol) for 106 μm and 250 μm size, respectively, for Langmuir, Freundlich and Temkin isotherms respectively. Conclusion: Therefore, Sorghum Hulls were found to be good adsorbent for Ni, Cu and Zn ions with mercaptoacetic acid modification increasing the sorption capacity." @default.
