微波改性的稻壳对Cr3＋吸附性能的研究
Study on the Removal of Cr3+ions from Aqueous Solution with Rice Husks Microwave Treatment
摘要
Abstract
The adsorption kinetics and thermodynamics mechanisms of single Cr3+systems on rice husks microwave treatment were studied in this paper.A set of experiments at various conditions, including solution pH, agitating time and metal ions concentration were conducted.In order to identify the possible mechanisms involved in metal i-ons binding by rice husks microwave treatment, chemical modification studies were performed along with SEM and FTIR analysis.Results indicated that the metal ions adsorption processed by rice husks microwave treatment has strong adsorption capacity and would be affected by pH value.When PH value is 5 and adsorption time within 60 min, it responded fast;and within 30 min, the reaction equilibrium can be established and the maximum adsorbing capacity for Cr3 +is 0.107 8 mmol/g.关键词
