| dc.description.abstract | Batch equilibrium and kinetics studies were carried out to study the rate and mechanism of dye uptake by commercial activated carbon. The percentage attrition (hardness),Bulk Density, Ash Content and methylene blue (mesoporosity) test were investigated. Comparison of the best fit model was made by evaluating the goodness of fit using the correlation coefficient values. (R2), sum of squares error (SSE) and the standard error (SE) of the estimate, which follow the trend, langmuir (R2=0.959, SSE=3.889, SE=3.118)>Freundlich (R2=0.901, SSE-9.449, SE=4.860). The smaller the values of SSE and SE, he better the curve fitting. Langmuir model gave the best curve fitting with smaller values of SSE and SE. The maximum theoretical adsorption capacity (q„J of the activated carbon was also evaluated using the Langmuir model the and the q^ was found to be 64.10 which shows that the activated carbon has a good adsorption capacity. The Elcmic and Intraparticle diffusion kinetic models were both applied to the adsorption kinetic data obtained. The Elovic equation gave the best fit with correlation coefficient of (0.995) and Intraparticle diffusion model (0.951). | en_US |
