| 摘 要： | 采用微波辐射技术结合酸、碱、盐分别对沸石进行活化改性处理,用分光光度法分析改性沸石对Fe2+的吸附性能及影响因素。结果表明:NaOH改性沸石对Fe2+的去除效果优于NaCl、HCl改性沸石,当微波功率为640W,微波时间为5min,NaOH浓度为0.8mol/L时,Fe2+去除率可达98.56%。经过对改性沸石再生,NaOH浸泡过的改性沸石再生性较好。

| Abstract: | The zeolites were respectively activated and modified by microwave combining with acid,alkali,salt,and the absorption property and influence factors of Fe2+ on zeolites were analyzed by spectrophtometry.The removal effect of modified zeolite by sodium hydroxide on Fe2+ was superior to that of sodium chloride and hydrochloric acid,and removal rate can reach 98.65% when the microwave power was 640W with the microwave time of 5min and the concentration of sodium hydroxide was 0.8 mol/L.The reproducibility of modified zeolite by sodium hydroxide was relatively better through the regeneration of modified zeolite. |
