Thiosemicarbazones are a class of schiff base acting as effective chelating agents. This paper presented applications of thiosemicarbazones in direct spectrophotometric method,extractive spectrophotometric method,kinetic photometric method,fluorometric method,flow injection spectrophotometric method and atomic absorption spectrophotometry. The related research and development were reviewed,such as spectral properties,analytical performances,applications and so on. It can be concluded that,after application the supramolecular chemistry principle to researching the relation between their properties and structures and to developing the performances of these functional molecules at the molecular level,not only the analytical reagents with better property can be well designed,but also the application scope can be broadened.
