| 中文摘要: |
| 制备了介孔二氧化硅纳米球（MSN），并将其用于吸附脱除水中的Mo（VI）。应用扫描电镜、介孔分析仪、红外光谱等对MSN进行了表征。考察了pH、吸附时间、MSN投加量和温度对水中Mo（VI）脱除率的影响，并在单因素试验基础上通过正交试验法确定了Mo（VI）的优化脱除条件：pH=3，MSN投加量为8.5g/L，吸附时间为36h，在此条件下MSN对加标水中Mo（VI）的脱除率为93.6%～97.3%。 |
| 英文摘要: |
| 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%. |
