Clay particles are frequently used in adsorption processes with aqueous solution, but the formed colloidal dispersion is responsible for several phenomena that hinder the flow. To overcome these problems, this work deals with adsorption experiments carried out using an adsorptive media prepared with clay immobilized on the surface of polymer pellets. The effect of biodiesel on three polymer pellets and on a clay‐polymer composite was evaluated. Only the composite was not affected by the biodiesel, and its optimal operational conditions were determined. The composite was effective to remove residual sodium from biodiesel, attaining levels below law requirements.
