【摘要】 本文提出一个测定钒的新极谱催化波体系.通过实验确定测定钒的最佳底液组成为:1.0×10^-5M 3,5-cl₂-DMPAP-0.03M NaBrO₃-0.001M H₂SO₄（pH=2.50±0.10）,线性范围为0.04～12ppb,对20多种常见离子的干扰进行了试验,将该体系应用于水和人发中痕量钒的测定,结果令人满意.该法具有灵敏度高、简便快速的特点.更多还原

【Abstract】 It has been found that a sensitive polarographic catalytic wave of vanadium is produced in the system of 3,5-Cl₂-DMPAP-NaBrO₃.The wave height is propor- tional to the concentration vanadium in the range 0,04-12ppb.The method has been developed for the determination of trace amounts of vanadium in water and human hair with good results.更多还原
