| 摘 要： | 在ｐＲ４．０的磷酸盐缓冲溶液中，５－溴水杨基荧光酮－Ｃｏ（Ⅱ）－ＣＴＭＡＢ可形成稳定的三元配合物．将此配合物预富集在玻碳电极表面，阴极溶出时可产生一个灵敏的吸附还原波，其还原峰电位在－０．７６Ｖ．峰电流与钴（Ⅱ）的浓度在５．０×１０－５－１．０×１０－７ｍｏｌ／Ｌ之间有良好的线性关系．

| Abstract: | A new and sensitive method for determining trace Co (Ⅱ) was deseribed in this paper. In the midium of phosphact (pH=4.0),5-bromosalicylfluoronc, cobalt (Ⅱ) and CTMAB formed a stationary ternary complex,which was perconcentrated on the surface of glassy carbon electrode and prqducted a scnsitive adsorptivc reduce wave as cathodic stripping at -0. 76V. The cathodic peak current was linear with the Co (Ⅱ) conccntration over the range of 5.0 ×10-5-10×10-7 mol / L. |
