摘      要：A new highly selective salicylate electrode based on N,N’-bis(3-nitrosalicylidene)-2,6-Pyridinediamine manganese(Ⅱ) complex[Mn(Ⅱ)-BNSPD]as neutral carrier is studied first,which displays an excellent electric potential response and an anti-Hofmeister selectivity sequence which is:Sal-SCN- ClO4- I- Br- NO3- Cl- NO2- SO32- SO42-.The electrode exhibits Nernstian potential linear range to salicylate from 1.0×10-1 to 6.0×10-6 mol·dm-3 with a detection limit 2.0×10-6 mol·dm-3 and a slope of 58.5 mV/dec in pH 5.0 of phosphorate buffer solution at 28℃.The electrode response mechanism is studied with the UV spectroscopy *** electrode is designed to be applied in medicine analysis with a satisfactory result worked out.
