Synthesis of New Chromogenic Reagent CAPPH and Its Studies on Determining Trace Cu 2+ in Sarcandra Glabra (Thunb) Nakai |

| Abstract: | We have synthesised the new chromogenic reagent 10 (2 carboxylphenylazo) 9 phenanthrahydroquinone,namely CAPPH,and studied the method in determining trace Cu 2+ of sarcandra Glabra (Thunb) Nakai by spectrophofometry.The results express that there is the most Cu 2+ content in stem,then in root,and the lest in leaf.Compared with atomic absorption spectrometry,the method not only is simple,and but also is accuracy. |
