In this study, mesoporous silica nanospheres (MSN) was prepared and used for the removal of Mo (Ⅵ) in water. MSN was characterized by scanning electron microscope, mesoporous analyzer and infrared spectroscopy. The effects of pH, adsorption time, adsorbent dosage and temperature on the removal rate of Mo (Ⅵ) in water were investigated, and the optimal removal condition of Mo (Ⅵ) determined by orthogonal test method was as follows:pH is 3.0, the adsorption time is 36h, MSN dosage is 8.5 g/L. Under optimized adsorption conditions, the removal rate of Mo (Ⅵ) in spiked water by MSN is 93.6%~97.3%.
