机械活化对渣分离ZnFe2O4微波处理罗丹明B的研究
Research on Mechanical Activation for ZnFe2O4 Separated from Slag in Processing Rhodamine B by Microwave
摘要
Abstract
In this paper,simulating industrial leaching process of zinc calcine and refine zinc ferrite from slag.Product 1 contains 98％ zinc ferrite and silicon,aluminum,antimony and other trace impurity elements in crystal structure.After mechanical activation got product 2 has multipoint BET specific surface area is 2.8249 m2/g,the average pore radius of single point is 15.66nm,and graded size distribute within the scope of 0.448 ～ 1.002 um and 1.002 ～ 10.024 um are 27.93％ and 53.48％ respectively with correlation coefficient is 0.999943.Compared treatment effect of pure zinc ferrite,product 1 and 2 to rhodamine B under the same condition,the results show that the adsorption capability for rhodamine B of ferrite zinc powder body stronger after mechanical activation.Adsorption-desorption process is greatly influenced by microwave power when it is less than 500 w,and degradation effect of microwave catalytic more apparent when power above 500 w.关键词
