Pharmaceutical and Personal Care Products (PPCPs) are considered emerging contaminants that present great challenges for their remediation from water. However, adsorption processes based on microporous materials could offer an efficient solution if tailored properly. In this study, the adsorptive removal of two emerging contaminants (salicylic acid and carbamazepine) from an aqueous solution was accomplished using a Faujasite-type synthetic zeolite modified with transition metals and a surfactant moiety. Co2+, Cu2+ or Ni2+ were employed to induce complexation-like adsorbate-adsorbent interactions at ambient conditions in an attempt to provide an efficient removal driving force in the low ppm range. The use of a surfactant is of utmost necessity given the highly hydrophilic nature of the zeolite. However, the adsorption equilibrium data clearly showed that the best capacities are obtained when a transition metal/surfactant combination is employed.
