Abstract
Using experimental data for the adsorption of phosphates out of wastewater on waste recycled bricks, published independently in MDPI Processes before (2020), this message re-visits the mathematical theory of the Freundlich adsorption model. It demonstrates how experimental data are to be deeper treated to model the saturation regime and to bridge a chasm between those areas where the data fit the Freundlich power function and where a saturation of surface adsorption centers occurs.

Where x, q, and q∞ stand for pressure, current adsorption, and limiting adsorption, respectively, the power of x is often considered as α = 1/n, where n > 0 is an integer or real number, in both historical and modern research can scarcely be overestimated
