| Abstract: | The color-reacting of Cu( 1 )with developer piperonal thiosemicarbazone (PTSC) is studied in this article. The molar absorbanly index of the yellow complex formed by Cu( 1 ) with PTSC is 7. 2 × 104. It comforms to beer law while copper content ranging from 0-20 μg/25ml. This method is suitable to measure copper with low content. |
