It was found that the adsorption efficiency of Ga(Ⅲ) was more than 96% at pH 3.0. The adsorption capacities and rates of Ga(Ⅲ) onto nano-TiO2 were evaluated as a function of solution concentration and temperature. The results were analyzed using the Langmuir adsorption isotherms. Adsorption isothermal data could be well interpreted by the Langmuir model. The mean energy of adsorption, 15.81 kJ·mol-1, was calculated from the D-R adsorption isotherm. The kinetic experimental data properly correlate with the pseudo-second-order kinetic model. The thermodynamic parameters for the process of adsorption have been estimated. The △ H Οand △ GΟvalues of gallium(Ⅲ) adsorption on nano-TiO2 showed an endothermic and spontaneous nature of adsorption.展开更多

The Naoxintong Capsule, a modern patent traditional Chinese medicine, is composed of Huangqi, Danshen, Quanxie, Shuizhi and other sixteen herbs. It is extensively used to treat coronary heart disease, stroke and other cardiovascular and cerebrovascular diseases, with the activity of anti-coagulation, anti-inflammatory, protecting endothelial cells, anti-atherogenic and plaque stabilization.展开更多
