Adsorption Of Blend Cationic Dyes By Activated Sludge

    The effects of dye molar ratio, ion concentration and sludge dosage on the adsorption of mixed dyes on sludge were investigated by using Langmuir and Freundlich equation pairs. Adsorption data were fitted.Blend Cationic Dyes

    The results show that the adsorption of sludge on the mixed dyes is in accordance with the pseudo-second-order kinetics. The adsorption capacity of the sludge can be determined by the sludge. The adsorption isotherm of the mixed dyes and the Freundlich equation The removal rate of the mixed dyes is between the removal rates of the two kinds of single-component dyes. When the sodium sulfate is less than 300mg / L, the removal rate of the two kinds of dyes is different. When the two kinds of dyes are mixed in different proportions, the removal rate of the mixed dyes is between the two kinds of single- , The increase of ion concentration promoted the removal of dyes, and the promoting effect was more than 300mg / L. After more than 600mg / L, the removal rate of mixed dyes became stable and was not affected by the concentration of sodium sulfate.
