A fundamental issue in beryllium research is the search for suitable chelating ligands for environmental and biomedical application. In this paper, the speciation of beryllium ions with several multidentate aminopolycarboxylic acids, which are well‐known commercial and biomedical chelating agents, has been investigated using electrospray ionisation mass spectrometry (ESI MS). Stoichiometric information
铍研究的一个基本问题是寻找适合环境和生物医学应用的螯合配体。本文使用电喷雾电离质谱(ESI MS)研究了铍离子与几种著名的商业和生物医学螯合剂多齿氨基聚羧酸的形态。从ESI质谱中容易获得的化学计量信息被发现对于通过单个配体的四齿配位对潜在的包封物进行初步筛选是有效的。ESI MS观察到的离子表明,与现有溶液形态数据一致,已存在的溶液种类和结合亲和力趋势被保留在气相中,这表明ESI MS的开发能力是快速,灵敏,安全的筛选技术,可观察到低浓度的目标配位体对铍的形成。也有报道称通过添加其他二价或三价金属阳离子会破坏铍-配体的结合。
