We prepared new morphine molecular imprinted polymer goethite nanorods (MMIPGN) which showed excellent adsorption properties due to presence of complementary cavities on the surface of polymer. MMIPGN was synthesized by using morphine as template, fumarate-functionalized goethite nanorods (FFGN) as auxiliary monomer, methcrylic acid (MAA) as functional monomer and ethylene glycol dimethacrylate (EGDMA) as a cross linker. The structural properties were characterized by Fourier transform infrared spectroscopy (FTIR), energy dispersive spectroscopy (EDS), field emission scanning electron microscopy (FESEM) and thermal gravimetric analysis (TGA). The adsorption behaviors of MMIPGN were monitored under various adsorption conditions such as contact time, pH, the amount of adsorbent and initial concentration of morphine. The selectivity of morphine by MMIPGN was investigated in the presence of foreign species such as epinephrine (Ep), ascorbic acid (Aa), and monoacetylmorphine (Mm) and the value of selectivity coefficients was obtained 1.19, 1.13, and 2.15, respectively. The experimental data were followed by Langmuir isotherm model and Elovich kinetic models
