示波极谱法测定地面水中的钒

DETERMINING VANADIUM IN SURFACE WATER BY POLAROGRAPHIC WARE

应用钒（ Ｖ）５ Ｂｒ Ｐ Ａ Ｄ Ａ Ｐ Ｈ２ Ｏ２ 体 系产生的 络合极 谱波对地 面水中 的钒 进行 了测 定，并 讨论了测试 条件。钒 浓度在 ００１ ～２２５ μｇ／２５ ｍ Ｌ 范围 内极谱 电流与钒 含量呈线 性关系 ，本法具有 较高的选择 性和灵 敏度，测定 地面水 中的钒结 果令人

Utilizing the adsorptive complex polarographic wave of V(v) 5 Br PADAP H 2O 2,vanadium in surface water was determined.The determination condition was discussed.The polarographic current is linearly to the concentration of V in the range of 0 01～2 25μg/25ml.The method is sensitive and selective.It has been applied to the determination of V in surface water with satisfactory results.
