Analysis of Composite Mobility Peak for Multiple Atmospheric Ions in Equilibrium
نویسنده
چکیده
ABSTRACT: Composite mobility peak of multiple ion families in the atmosphere predicted by Mohnen [Mohnen, 1977] has analytically been obtained using a general solution of coupled diffusionreaction equations governing the spatiotemporal evolution of the number densities of an arbitrary number of ionic species. In model analysis at dynamic equilibrium, three discrete mobility spectra can be numerically obtained, where each mobility peak contains three ionic species. The analysis is applicable to real atmospheric ion-systems such as composite ammonium ion and hydronium (oxonium) ion families.

Statistical physics modeling of equilibrium adsorption of cadmium ions onto activated carbon, chitosan and chitosan/activated carbon composite
The adsorption ability of activated carbon, chitosan, and chitosan/activated carbon composite for cadmium separation from aqueous solution was analyzed via statistical physical modeling. The equilibrium data were analyzed by Langmuir, Hill, double layer model, and the multi-layer model with saturation isotherm models. Results showed that the multi-layer model with saturation could well describe...
