Magnetic nanoparticles based dispersive micro-solid-phase extraction as a novel technique for coextraction of acidic and basic drugs from biological fluids and waste water

•A novel strategy for coextraction of acidic and basic drugs is proposed.•The method relies on magnetic nanoparticles dispersive micro solid phase extraction.•Cetyltrimethyl ammonium bromide-coated Fe3O4@decanoic acid was used as a sorbent.•A very short extraction time and a small amount of organic...
