Abstract	The adsorption equilibrium and Kinetic modelling of pigment extracted from Fenugreek after degumming on macroporous resins LS-46 was investigated under differentinitial concentrations. The suitability of the Freundlich and Langmuir adsorption models to the equilibrium data was investigated. The model fitness was determined by R2. Kinetic analyses were conducted using pseudo firstand second-order models and the intraparticle diffusion model. The results showed that Freundlich model gave a better fit of adsorption isotherms than Langmuir models. Adsorption kinetics were more accurately represented by a pseudo one-order model and the intraparticle diffusion model, the adsorption process is mainly controlled by the step of liquid film diffusion, and by the combined effect of intraparticle diffusion.
