Molybdenum-containing Wastewater Treatment Effect of Fly Ash and its Adsorption Mechanism AITranslate
Abstract AITranslate
Molybdenum removal experiments of simulated molybdenum-containing wastewater were carried out with fly ash as the absorbent. Influences of absorption pH and absorbent dosage on adsorption results were studied, and the adsorption isotherm equation and kinetics were discussed. The results show that the adsorption effect of fly ash for molybdenum is best with a molybdenum removal rate of 74.3 %, under the conditions of molybdenum initial concentration 10 mg/L and pH=8.1. The addtion of 2.5 g absorbent into 50 mL molybdenum-containing solution resultes in optium molybdenum removal up to 85.4%. Molybdenum adsorption on fly ash conforms with Langmuir adsorption isotherm equation, dominated by surface single-molecule layer adsorption. The adsorption kinetic data are fitted with second-order kinetic model, representing the characteristics of both physical adsorption and chemisorption.
