研究了锆(IV)/8-羟基喹啉-5-磺酸(HQS)/EDTA三元混配络合体系,发现EDTA具有显著改善灵敏度与提高选择性的双重功能.建立了锆的选择性好灵敏度高的荧光测定方法,并用于合成和合金样品分析,可不经分离.
The complexation of zirconium (IV) / 8-hydroxyquinoline-5-sulfonic acid (HQS) / EDTA ternary complex was studied and it was found that EDTA has the dual function of significantly improving the sensitivity and improving the selectivity. Good sensitivity of the fluorescence determination method, and for the synthesis and analysis of alloy samples, without isolation.
