摘要: Equilibrium and kinetic behavior of two basic dyes, Methylene Blue (MB) Safranine T (ST), onto calcite in single binary component systems have been studied. Experimental equilibrium results well predicted by the Freundlich Langmuir isotherm models. The model parameters obtained for solute at 298 K used calculation adsorption isotherms dye solutions using multi-component Extended extended models satisfactorily fit to MB–ST solutions. A site distribution function which gives information about affinity sites competing species a system has mathematically calculated parameters. Time-dependent analyzed according Vermeulen McKay based on homogeneous heterogeneous diffusion processes, respectively. Thermodynamic functions transition s...
