CrS@酵母复合吸附剂对亚甲基蓝的吸附特性研究

Study of the adsorption properties of methylene blue wastewater by the composite adsorbents of CrS@ yeasts

研究了CrS@酵母复合吸附剂对阳离子型染料亚甲基蓝的吸附性能,考察了在不同pH值、流速V、床高H、初始浓度c_0条件下对亚甲基蓝染料的吸附效果,以探究最佳吸附条件。结果表明,在溶液pH值为3,流速5 m L/min,床高H=1.5 cm,初始浓度c=50 mg/L时吸附效果最好。采用动力学模型Yoon-Nelson对不同条件下吸附曲线进行分析,相关系数R^2均大于0.9,本次研究结果对于甲基蓝废水的处理具有很重要的参考价值,并且对于我国染料废水的处理可提供借鉴。

CrS@ yeast composite adsorbents were used to treat the methylene blue aqueous solutions. Factors affecting the adsorption process,such as different p H values,flow velocity V,bed height H,initial concentration c_0 were investigated respectively,which to explore the best adsorption conditions. Results show that the solution pH = 3,velocity 5 m L / min,the bed height H = 1. 5 cm,the initial concentration c_0=50 mg / L can reach the best adsorption condition. And this experiment uses kinetic model Yoon-Nelson to analyze the adsorption curve under different conditions,correlation coefficient R2 0. 9. The results of this study for the methylene blue wastewater treatment has a very important reference value,and give some reference for the treatment of dye wastewater.
