Mechanism study on acid blue adsorption on mold/fly ash composite
摘要
Abstract
This study focused on the application of treating acid blue dye wastewater with a new adsorbent compound with mold/fly ash. Single factor experiments were conducted to investigate the adsorption conditions and mechanism of acid blue through. The results showed that the removing rate was above 85% under the conditions of dosage of composite absorbent 3 g/L; pH 6.6; stirring time 25 min; and standing time 1 h. The acid blue adsorption agreed with Langmuir and Freundlich adsorption models, and it fitted Freundlich thermostatic adsorption equation better. The adsorption parameters showed that the adsorption of composite adsorbent on acid blue was monolayer adsorption, and the saturated adsorption capacity can be obtained as 303.03 mg/g. The adsorption kinetic of acid blue system fitted second-order kinetics with a saturated adsorption capacity of 137.32 mg/g. The adsorption was chemic-sorption.关键词
