硫脲类试剂是有机试剂中近年来迅速发展的一类试剂，尤其是芳基硫脲和杂环取代基硫脲在分析化学中得到广泛应用。本文综述了近二十年来芳基和杂环取代基硫脲的性质及其在分析化学中的应用现状．
Thiourea reagent is a kind of reagent which has developed rapidly in recent years in organic reagents, especially arylthiourea and heterocyclic thiourea, which have been widely used in analytical chemistry. This review summarizes the properties of aryl- and heterocyclic-substituted thioureas and their applications in analytical chemistry in the last two decades.
