摘　　要：综述了2003～2009年国内外利用不同分析测试技术测定痕量镍的进展,并对常规分光光度法、催化动力学光度法、原子吸收光谱法及电化学分析等方法进行重点讨论。从反应体系、反应介质、灵敏度、线性范围等方面归纳了上述测定体系在实际样品中的应用情况。为了克服分离手段复杂、数据处理复杂等缺点,需要开发诸如简单的分离富集技术与仪器联用等新技术并将化学计量学运用到各种技术当中。此外,研制新的灵敏度高、选择性强及稳定性好的活化剂和探针,也是提高测定镍含量准确度的可行手段。The development of determination of trace nickel was reviewed using different analysis test technology from 2003 to 2009, focusing on conventional spectrophotometry method, catalytic kinetic spectrophotometry, atomic absorption spectrometry, electroanalytical method and so forth. The application of the above determination systems to actual samples was concluded from many respects such as reaction system, reaction medium, sensitivity, linearity range and so on. In order to overcome the shortcomings of complicated separation method and complex data processing, a series of new technology such as the combination of simple separation and enrichment technology with instrument need to be developed, and stoichiometry should be applied to these technologies. Furthermore, exploiting the new activators and probes with high sensitivity, selectivity and stability should also be a feasible means to improve the accuracy of determining nickel.
