Keywords:Lead, Adsorption Kinetics, Microsoft Excel Solver, Analysis of Variance, Mass of Adsorbents, Significant Factors
This paper presents a report on the removal of lead ions (Pb2+) from aqueous solutions through adsorption techniques using powdered corncobs. Corncobs were collected from Obafemi Awolowo University agricultural farm. The corncobs were washed with distilled water to remove impurities. The corncobs were dried at room temperature, pulverized, sieved into different particle sizes using standard sieve sizes and stored. Powdered corncobs (PCCS) were separated based on the size. Its micrograph structure, physical and chemical properties were determined using standard methods. The PCCS was used as an adsorbent to remove Pb2+ from aqueous solutions and raw water through batch processes. Effects of the mass of the adsorbent, the initial concentration of Pb2+, initial pH of the aqueous solution and particle size of PCCS on the adsorption kinetics and its modelsâ€™ parameters were evaluated.
The study shown that moisture content of the PCCS was 7.29 %, volatile solid at 550oC and 1200oC were 96.88 % and 99.44 % respectively. It was also revealed that mass of adsorbent, pH, particle size of the adsorbent, initial concentration of Pb2+ and adsorption time were significant factors that had effects on adsorption of Pb2+ onto PCCS at 95 % confidence level. It was concluded that lead ion can be removed by PCCS, the mass of the adsorbent had significant effects on adsorption kinetics.
