The research work sought to identify the most efficient preparation method, in terms of adsorption, for obtaining activated carbon using olive pits. Along these lines, 3 preparations were carried out: chemical activation, activation by sonication and obtaining biochar. For the adsorption experiments, the 3 samples underwent the same conditions of phosphate removal in liquid effluents, namely temperature, removal time, initial phosphate concentration and sample quantity. These conditions were carried out to ensure the correct comparison between the removal efficiencies. The results showed that the sonicated biochar has the highest removal efficiency, followed by activated carbon and ending with biochar in the 2 scenarios of initial phosphate concentration: 50 ppm: qt = 16; 4 and 3.5, respectively / 20 ppm: qt = 9.5; 4 and 2.5, respectively. From the characterization of the 3 samples, it was found that the presence of ZnO on the surface of the sonicated biochar would have favored the adhesion of the phosphates to the sample. This adhesion was due to the sonication process that the sample underwent during its preparation stage, which indicates that sonication improves the adsorption of a biochar because this process generates the breaking of bonds between the impurities of the charcoal and the improvement of the surface area.
