炭化茶渣的制备及其对罗丹明B的吸附性能研究

AbstractVarious processing of tea leaves leads to the production of a large number of tealeaves,and the number of tea leaves is increasing year by year.How to effectively andsafely handle tea leaves has become the focus of more and more researchers.Tealeaves are a kind of absorbent with large surface area and porous network structure.Inthis paper,the adsorption properties of industrial tea leaves after washing,drying ordrying were studied,and the adsorption properties of rhodamine B solution withdifferent concentrations were studied after carbonization The following conclusionsare drawn:0.8 g carbonized tea leaves were placed in 80 mL rhodamine B solutionwith a concentration of 1x105 mol/L.With the adsorption reaction,the peak at 554nm in the uv-visible absorption peak decreased continuously,and the adsorptionefficiency of carbonized tea leaves on rhodamine B could reach 77.37%within 60min.Key words:Industrial dross,carbonized,absorption,Rhodamine B
