  • Forming ultrafine coal flyashbased adsorbent(FUFA) was prepared from coal flyash. Dynamic adsorption of methylene blue (MB) and Cr6+ on the adsorbent was studied. Breakthrough curve was drawed, and the experimental data were dealt by Origin software to get the model of breakthrough curve equation(Ct=A1-A2〖〗1+(t/t0)p+A1).The results showed that when initial concentration was 25 mg/L with varying filling height, the time to penetration point increased with filling height increased. When the filling height was 200 mm with different initial concentration, the time to penetration point reduced with initial concentration increased. The adsorbent had better capacity for both organic dye and heavy metals ion. It indicated that this model was fit for the dynamic adsorption of MB and Cr6+ on the FUFA by linear correlative coefficient of breakthrough curve.

Dynamic adsorption experiments of forming ultrafine coal flyash-based adsorbent

Fund Project:

Abstract: Forming ultrafine coal flyashbased adsorbent(FUFA) was prepared from coal flyash. Dynamic adsorption of methylene blue (MB) and Cr6+ on the adsorbent was studied. Breakthrough curve was drawed, and the experimental data were dealt by Origin software to get the model of breakthrough curve equation(Ct=A1-A2〖〗1+(t/t0)p+A1).The results showed that when initial concentration was 25 mg/L with varying filling height, the time to penetration point increased with filling height increased. When the filling height was 200 mm with different initial concentration, the time to penetration point reduced with initial concentration increased. The adsorbent had better capacity for both organic dye and heavy metals ion. It indicated that this model was fit for the dynamic adsorption of MB and Cr6+ on the FUFA by linear correlative coefficient of breakthrough curve.
