传统方法铜的测定常用铜试剂光度法、溶剂萃取光度法、原子吸收光谱法等，但由于铜离子在水中微量存在，经常要求测定mg／L甚至μg／L级的痕量数据，由于分析仪器的灵敏度及检出限的关系，许多仪器在测定这些试样时会遇到困难，本文着重阐述了痕量铜离子的测定进展，对于痕量铜的测定具有指导意义。

Copper reagent spectrophotometry , solvent extraction spectrophotometry and atomic absorption spectrometry are the traditional methods for the determination of copper.Because of the copper ion in trace amounts of water, trace data usually requires the determination of mg/L even μg/L level, due to the sensitivity analysis instrument and detection limit , many instruments will encounter difficulties in the determination of these specimens.The determination of trace copper ion was studied , in order to directive significance for the determination of trace copper ion.
