摘要：In this study, fly ash was modified using sulphur to remove Rhodamine B(RB)from aqueous solution. This paper discussed the influence of adsorption time, modified fly ash dosage, pH value, initial concentration on the removal efficiencies. The results showed that 50.0 mL RB wastewater whose concentration was 10.0 mg/L, the adsorbent dosage was 0.3000 g, the pH was 2.0, adsorption time was 60.0 min, the removal efficiencies(RE) and elimination capacity (EC) were 84.68% and 1.41 mg/L, respectivly. The modified fly ash adsorption of RB obeyed the Freundlich isotherm equation, belong to the multilayer adsorption. The adsorption process was accorded with second kinetics reaction of Lagergren. The results implied that fly ash can be effective used as adsorbent to RB wastewater.
