CGA浮选亚甲基蓝离子的浮选动力学研究

Studies on Flotation Kinetics of Methylene Blue Ion using CGA

应用由ＮａＬＳ制成的胶体泡沫（ＣＧＡ）对水溶液中的亚甲基蓝（ＭｅＢ）进行离子浮选，以吸附动力学为基础建立了ＣＧＡ浮选动力学模型，并研究了其动力学规律，计算了浮选速度常数，讨论了被浮选液的ｐＨ、中性盐浓度、表面活性剂浓度以及ＣＧＡ流量对浮选速度常数的影响。

This paper presents the application of the CGA prepared with NaLS to float methylene blue ion from its aqueous solutions.A model of flotation kinetics on the basis of surface adsorption kinetics was established,and the mechanism of the flotation kinetics was also discussed.Flotation rate constants were calculated and the effect of aqueous solutions'pH value,concentration of NaC1 and concentration of NaLS used to prepare for the CGA on the flotation rate constants were discussed.
