摘要:

研究采用镁铝层状双（氢）氧化物（MgAl-LDH）及其焙烧产物（MgAl-LDO）去除水溶液中的亚铁氰离子（[Fe(CN)6]4-）。采用共沉淀法制备了不同CO2-3、Cl-插层浓度的MgAl-LDH，并通过焙烧法制备了不同的MgAl-LDO。探究了LDH及LDO对[Fe(CN)6]4-的吸附性能。结果表明:LDH具有较快的吸附速率，可在20 min内实现吸附平衡；LDO具有较高的吸附容量，最高为234.4 mg/g；在pH值为7~12时，吸附剂对[Fe(CN)6]4-均有较好的吸附效果；在含有高浓度SO2-4及SCN-溶液中，吸附剂能实现[Fe(CN)6]4-的选择性吸附。对反应机理的分析表明：在LDH的插层阴离子中，只有Cl-能与[Fe(CN)6]4-发生离子交换产生吸附效果，并生成Al[FeMg(CN)6]；LDO对[Fe(CN)6]4-的吸附作用源于其“记忆效应”，LDH层间CO2-3占比越高，相应LDO的吸附容量越大。

Abstract:

This study investigates the removal of ferrocyanide ions ([Fe(CN)6]4-) from aqueous solutions using MgAl layered double (hydro)oxides(MgAl-LDH) and their roasting products (MgAl-LDO).MgAl-LDH with different concentrations of CO2-3 and Cl- intercalates were synthesized by co-precipitation, and various MgAl-LDO were prepared by roasting. The adsorption performance of LDH and LDO for [Fe(CN)6]4-was explored.The results show that LDH exhibits a rapid adsorption rate,achieving equilibrium within 20 min. LDO has a higher adsorption capacity,reaching a maximum of 234.4 mg/g.The adsorption is effective at pH values between 7 and 12.The adsorbent also demonstrates selective adsorption of [Fe(CN)6]4-in solutions containing high concentrations of SO2-4 and SCN-.Mechanism analysis indicates that in LDH intercalated anions,only Cl- can exchange with [Fe(CN)6]4-,leading to adsorption and forming Al[FeMg(CN)6].The adsorption of [Fe(CN)6]4-by LDO is attributed to its memory effect with higher CO2-3 content in LDH layers corresponding to greater adsorption capacity of LDO.
