| 摘 要： | 本提出了以均苯四甲酸为配体的铽的荧光测定法，试验表明：在ｐＨ＝６．０－９．０的缓冲溶液中，钆离子能明显增强Ｔｂ＾３＋－均苯四甲酸二元体系的荧光强度。该体系已用于痕量铽的测定，其检出限为４×１０＾－９ｍｏｌ／Ｌ。

| Abstract: | The fluorimetric determination of terbium using pyromellitic acid as the ligand is put forward. The experimental result showed that gadolinium ion could distinctly enhance the fluorescence intensity of the Tb-pyromellitic acid binary system in the buffer solution at pH 6. 0-9. 0. This system has been applied to the determination of trace terbium. The detection limit of terbium was 4*10-9 mol/L. |
