  • The removal of total phenolic compounds (TPC) from olive mill wastewater (OMWW) was studied by sorption under the conditions of conventional and microwave on previously characterized soils. The sorption process was studied in batch using inorganic materials (soils) in their natural states for sustainable development. The characterizations of the soils have shown variability in the potential of hydrogen (4.6-8.9), in total nitrogen, which is between 0.2 and 2.5%, and in mineral matter, which varies between 6 and 15%. On the other hand, the mineralogical characterization showed that the three adsorbents are composed of several clay and non-clay minerals. The experimental data were analyzed using the reaction and diffusional models. The pseudo-second-order kinetic model provides the best correlation for the three natural adsorbents denoted G (gray), B (black), and R’ (red). The sorption models of Langmuir, Freundlich, and Dubinin-Radushkevich were used for the mathematical description of the conventional adsorption equilibrium. The best correlations were obtained with the Langmuir model (r2 > 0.95) on the G and B adsorbents, unlike the Freundlich and Dubinin-Radushkevich models (r2 < 0.64). The adsorbent R’ can be represented by the Freundlich model (r2 ≥ 0.96) and the Langmuir model (r2 > 0.94). The latter is confirmed by the value of the dimensionless coefficient RL. The removal rates of TPC were calculated, and the value obtained (71%) shows that the G adsorbent is a good adsorbent. The results are satisfactory and promising.
