Abstract:
The aim of the present work is the adsorption of the blue dye from wastewater onto activated carbon by using continuous system (fixed-activated carbon bed). Continuous adsorption experiments of fixed bed were carried out to study the effects of (flow rate Q, initial dye concentration C?, bed depth Z, and carbon particle size P.s) on the adsorption capacity and performance of fixed bed adsorber.
Adsorption through granular activated carbon was found to be very effective for the removal of the blue dye, where the percent dye removal was 90%.
The equilibrium data were determined experimentally and the equilibrium isotherm was found to be of a favorable type and fit well by Langmuir and Freundlich isotherms. The study was developed a multiple linear regression model between the independent variables (Q, C?, Z, P.S) and the dependent variables (Time t, Amount of adsorbate q) separately, the verification and the correlation coefficient (R) (0.92, and 0.95) for these correlation respectively, illustrate that the experimental data correlated well with the modeling data.
Batch process was carried out to obtain the surface diffusivity by comparing the experimental and theoretical results of the fractional uptake.
