Study on dynamic adsorption of methylene blue by aged-refuse

Abstract

The performance of dynamic adsorption and the effects of height of filler, MB initial concentration and flow rate on the breakthrough curves were investigated by the dynamic adsorption experiment of the filler column. The results showed: Aged-refuse can effectively adsorb MB in the water, with the increase of filler height, the breakthrough point in the curve move toward the right and the breakthrough time is prolonged. Whereas, with the increase of flow rate and MB initial concentration, the breakthrough point of the curve shifts toward the left and the breakthrough time is shortened. The adsorption process in the initial phase conforms to Adams-Bohart model. The effect of sorbent height on removal MB can be well described by BDST model.
