The presence of pharmaceutical substances in aqueous effluents represents one of the major concerns in environmental protection, as most of them present a profound endocrine disrupting character. The present study evaluates the use of organic/ inorganic core-shell magnetic composites for the removal of two types of endocrine disrupting pharmaceutical substances. The results presented show a good affinity of the nickel ferrite/chitosan composite towards the adsorption of Na naproxen (89% at 48 h), while the best results for the adsorption of diltiazem HCl were obtained for the copper ferrite/chitosan composite (56% at 48 h); in the same time, the magnetic properties of the composites allow the easy removal of the adsorbents from the aqueous effluents.
