Factors Influencing Textile Dye Absorption of Dylon Blue Dye on Activated Carbon

The research is dedicated to studies of activated carbons performance in the wastewater process of dye removal. The experiment was performed to assess the efficiency of the commercial activated carbons (Fl00, F600, F820, SGL 8x30, CAL, AP4-60, OLC12x30) in adsorption process for Dylon Blue Dye. The effect of type of activated carbon, dye, salinity, pH and contact time, were studied. Minitab software was used to design an experiment to collectively evaluate these factors. The experiments were performed by measuring the absorbances of the solutions before and after contact with the activated carbon. The absorbance was evaluated with UV-Vis spectrophotometer. The adsorption of the dye took place on all the studied activated carbon samples, thus the dye concentration reduced comparing to the initial solutions. Results of the study indicated that pH and salinity did not have any significant effect of the adsorption of the dye on the carbon. However, type of carbon and contact time were shown to influence adsorption significantly. Lack of effect of pH and salinity in current study contrasts finding reported in other studies
