摘要
锶的选择性富集对液态锶资源的开发具有重要意义。冠醚因其对金属离子具有特异选择性而被广泛用于资源回收、离子识别等领域。18-冠-6及其衍生物与Sr^(2+)因具有相匹配的尺寸而被认为是极具发展潜力的Sr^(2+)富集材料。综述了液液萃取、固液吸附、冠醚耦合工艺对Sr^(2+)富集的主要方法及优缺点。通过对现在富集工艺进行总结,展望基于冠醚化学法Sr^(2+)富集的未来发展趋势。
The selective enrichment of strontium holds significant importance for the development of liquid strontium resources.Crown ethers,renowned for their specific selectivity towards metal ions,find wide applications in resource recovery,ion recognition,and related fields.Among them,18-crown-6 and its derivatives,with matched sizes to Sr^(2+)ions,are considered highly promising materials for Sr^(2+)enrichment.This review article incorporates the main methods and advantages/disadvantages of Sr^(2+)enrichment using liquid-liquid extraction,solid-liquid adsorption,and crown ether coupling processes.By summarizing the current enrichment techniques,this review also outlines future trends in Sr^(2+)enrichment based on crown ether chemistry.
