A simplified method is proposed which enables the determination of solid diffusion coefficient for systems with non‐linear adsorption isotherm. The method involves the approximation of the concentration history of the liquid phase with polynominal functions and consequently the match of the experimental results and calculated values. Experimental work has given rather satisfactory results.
