In this study, silica-coated magnetic nanoparticles modified with N-methyl-D-glucamine (NMDG) were synthesized by a sol�gel method. These magnetic nanoparticles were assessed as a new solid phase extractant for extraction of boron from aqueous solutions. The crystal and chemical structures and magnetic property of the new extractant were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), Fourier transform infrared spectrophotometer (FT-IR), and vibration sample magnetometer (VSM). The synthesized extractant were applied to extraction of boron from different water samples. The influence of different parameters on the exractant capacity, magnetic exractant dosage, pH, equilibrium time, type and amount of stripping solution, were evaluated by using the magnetic extractant.
