The development of spectrophotometriodetermination of lead（Ⅱ） is reviewed. The main analysis methods include conventional spectrophotometry, catalytic kinetic spectrophotometry , inhibition kinetic spectrophotometry, fluorescence spectrophotometry , resonance light scattering, chemiluminescence analysis and coupling technique. The system, condition, linear range, detection limit and applications of each method are summarized. The development trend of spectrophotometric method for the determination of lead（Ⅱ） in the future is also discussed. Firstly, the reaction mechanism was explored for the purpose of setting up a novel reasonable and simple spectrophotometrie analysis system of lead（Ⅱ） to improve selectivity and reproducibility. Secondly, new chromogenic reagents were developed which are of high sensitivity, selectivity, stability, and non or low toxicity to improve detection methods. Thirdly, by combining with the high effective separation and enrichment technology analytical process was simplified to reduce interference, realizing the accurate determination of trace lead（Ⅱ）.
