| Abstract: | Study on adsorption kinetics and thermodynamics of salicylic acid by NDA 100 macroreticular resin was carried out through static experiments. The results showed thait the adsorption rate for the solute appear to be the first order kinetics, the intraparticle diffusion is the main rate controlling step. The adsorption date fit well into the Langmuir and Freundlich adsorption isotherm, the uptake of salicylic acid on NDA 100 macroreticular resin is a type of physical adsorption. |
