In this study, ZnO nanoparticles made by hydrothermal method for adsorption of phosphate fromwater. These ZnO nanorods are characterized by a powder X-ray diffraction spectroscopy (XRD),scanning electron microscope (SEM), specific surface area (BET), energy dispersive X-rayspectroscopy (EDS). The ZnO materials were applied for adsorption of phosphate from water usingbatch experiments. The effects of pH (4 - 10), adsorption time (30 - 240 min), the amount of adsorbent(0.005 - 0.035 g), and initial concentration of phosphate (147.637 - 466.209 mg/L) on the adsorptionwere investigated. The optimum condition was found at pH = 5, at adsorption time of 150 min. Theadsorption was fitted well with Langmuir isotherm and the maximum adsorption capacity wascalculated to be 769.23mg/g. These results show that ZnO material would be a very promising materialfor adsorption of phosphate from water.Keywords: ZnO, nanoparticles, hydrothermal methodfor, phosphate, Aqueous solution.
