- Abstract
This information add to database an attempt to model the adsorption of dye from dyeing wastewater in relationship to certain established energy parameters. The adsorbent is thermochemically cracked shea nut shell activated carbon, the adsorbate is textile dyestuff wastewater from Chellco textile ltd., Kaduna, Nigeria. The process is batch adsorption test while the adopted models are Rudishkevich - Dubinin and Temkin isotherms. This critical study which utilizes these more recent adsorption isotherms was found to present the mean free energy values (ED =1.036 - 1.406 kJmol-1) as a direct proportionality to the theoretical saturation capacities (qD = 2.032 - 4.169mgg-1). Sorption energy values proves to be higher for biosorbent, SS/A/15 (1.364 KJmol-1) ,which also gave the corresponding higher adsorption capacity (4.169 mgg-1) than the other three biosorbent in the series. A thermodynamic parameter (ΔG) was investigated to be more negative with sorbent - dye contact time, within the equilibration limit. The Close similarities of analytical results to those reported in reviewed literature, and the good degree of adsorption is an indication that using shea nut shells as a low cost biomass for generating activated carbon could be a feasible outlet in bioremediation.
