采用玻碳电极直接扫描测定Sb,不能用于微量Sb的测定,即使采用镀金属膜的玻碳电极也达不到。本文在示波极谱仪上试验了在静态溶液中,于较负电位上阳极化导数扫描预富集微量Sb,然后于扫描休止时间内,迅速转换原点电位至较正电位上,进行微量Sb的阳极化导数扫描测定,获得了较满意的结果。测定线性范围为0.004～0.3μg/ml。本法比文献所 Glassy carbon electrode direct scanning determination of Sb, can not be used for the determination of trace Sb, even with a metal-coated glassy carbon electrode can not reach. In this paper, the oscillopolarography was tested in a static solution, at a more negative potential anodic conductance sweep pre-enrichment of trace Sb, and then in the scanning of the rest time, quickly switch the origin to a more positive potential, the amount of Sb The anodic derivative of the scanning determination, obtained more satisfactory results. The linear range was 0.004 ~ 0.3μg / ml. The law than the literature
