The adsorption kinetica of crystal violet (CV) on silver mirror and two different kinds of silver sols is studied. The adsorption of CV on silver is homogeneous. It is confirmed that the topography of the surface affects only adsorption rate constant, while it does not change heterogeneity parameter. The similar behavior of enhancement factor and adsorption rate constant of CV in the two silver sols is discussed. The adsorption energy of CV and the concentration of adsorbed sites on the surface are estimated by adsorption isotherm. It is found that the enhancement effect on the silver mirror is determined by the concentration of adsorbed sites on surface. 相似文献

利用核物理方法进行地球物理测井,称为核测井.核测井是以研究岩石及其孔隙流体的某种核物理性质为基础的.核测井与其它测井方法(如电法测井、声波测井等)相比,具有独特的优点.它既可以在裸眼井中又可以在套管井中测量,而且不受井内介质的限制.因此,它在测井中得到越来越广泛的应用.核测井方法有许多种,概括起来可以分为三大类,即伽马测井、中子测井和同位素示踪测井. 相似文献
