| 摘 要： | 以油页岩灰渣为研究对象,采用碱熔-水热合成法合成P型沸石,研究了灰碱比、碱熔温度、水热温度、NaCl添加量等条件对合成P型沸石的影响,并利用制备的P型沸石进行了对Co2+的吸附性能试验,结果表明,NaCl的添加有利于沸石合成,而灰碱比、碱熔温度、水热温度的提高不利于沸石合成。油页岩灰渣与P型沸石对废水中Co2+的去除率都随着吸附剂投加量的增加而呈上升趋势。P型沸石对Co2+的吸附性能优于油页岩灰渣。并且随着Co2+溶液初始浓度的增加,P型沸石对Co2+的去除率逐步递减。

| Abstract: | The thesis takes oil shale ash as the research object, adopts alkali fusion-hydrothermal synthesis method to synthesize P-type zeolite, and studies the influence of ash-alkali ratio, alkali fusion temperature, hydrothermal temperature, NaCl addition amount, and other conditions on the synthesis of P-type zeolite. And using the prepared P-type zeolite to carry out the Co2+ adsorption experiment. The results show that the addition of NaCl is beneficial to the synthesis of zeolite, while the increase in the ash-alkali ratio, alkali fusion temperature, and hydrothermal temperature is not conducive to the synthesis of zeolite. The removal rate of Co2+ in wastewater by oil shale ash and P-type zeolite shows an upward trend with the increase of adsorbent dosage. The adsorption performance of P-type zeolite for Co2+ is better than that of oil shale ash. And with the increase of the initial concentration of Co2+ solution, the removal rate of Co2+ by P-type zeolite gradually decreases. |
