提出了钒-焦性没食子酸体系树脂相分光光度法测定痕量锐的方法。灵敏度高（ε590=5．6×104L·mol－1·cm－1），选择性好．测定范围为0～1．4mg·L－1。实测了天然水中的钒．结果令人满意。
The method of resin phase spectrophotometry for the determination of trace amounts of vanadium-pyrogallol was proposed. High sensitivity (ε590 = 5.6 × 104L · mol-1 · cm-1), good selectivity. The measurement range is 0 ~ 1.4mg · L-1. Measured the natural water of vanadium. The result is satisfactory.
