A simple and sensitive, solid-phase extraction method for the removal of Citalopram drug from wastewater has been developed by using magnetic nanoparticles modified with surfactant sodium dodecyl sulfate. Thesemagnetic nanoparticles have shown great adsorptive tendency towards Citalopram drug. The effect of differentparameters influencing the extraction efficiency of this drug were investigated and optimized including the pH,amount of the surfactant, contact time and temperature. The extracts were analyzed by ultraviolet spectrophotometryat nm. Under these conditions, the related standard deviation (RSD %) of the method at two concentrations ( andμg.mL- ) was in the range of ( – ) % (n = ). The calibration curve was linear in the range of - μg.mL-of Citalopram drug with a correlation coefficient of > .
