Effects of Process Variables on the Adsorption of Heavy Metals from Coal Effluent Using Cowbone-Derived Adsorbent.
Abstract
This research work was centered on the Effects of Process Variables on the Adsorption of Heavy Metals on Cowbone Granules. Carbonization of the cowbone sample was achieved at a controlled temperature of 500oC, while a granular size of 500µm of the carbonized cowbone was generated by means of micro sieves. Acid activation was achieved through hydrochloric acid impregnation at different molarities of 0.2, 0.5 and 1.0g/mol for respective samples of cowbone adsorbent (A1, A2, A3), at varying dosages of 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0g. In each experiment, 20ml of the coal effluent of known total contaminant concentration was treated with 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0g respectively, for similar variation of adsorbent dosages and contact times of 5, 10,15,20, 25, 30 and 35minutes. The concentration values were found to decrease with increase in time,while the adsorption efficiency was observed to be best (97.38 %) within the adsorption times of 20 to 25 minutes, and adsorbance was found to increase in the direction of increasing dosage. Large amount of contaminants was also found to be adsorbed in the first 20 minutes of contact time. This initial fast rate of adsorption was attributed to the availability of several binding sites for solute uptake. Generally, adsorption of heavy metals from coal effluent, using cowbone-derived adsorbent was found to be largely dependent on process variables, such as Concentration, Dosage and Contact Time.
