摘要：

N,N',N",N'" 1,5,8,12-tetraazadodecane-bis(salicylaldiminato)(H2L) has been used as ionophore for preparing Mn2+ selective sensor. Membranes of different composition with regard to ratio of H2L:PVC:NPOE:NaTPB have been prepared and investigated. The best performance was obtained with the membrane of composition 10:150:150:10 (H2L:PVC:NPOE:NaTPB) (w/w; mg). This membrane generated linear potential response in the concentration range of 5.0 x 10(-6) to 1.0 x 10(-1) M with a Nernstian slope of 30.0 mV/decade of activity and fast response time (10 s). Hydrogen ion does not effect to the performance of sensor in the pH range 3.0-6.5. The sensor was found to be sufficient selective for Mn2+ over a number of alkali, alkaline and heavy metal ions and could therefore be used for the determination of manganese in various samples by direct potentiometry.
