PURPOSE:To permit the selective measurement of adenosine diphosphate by using a specific bicyclo di-ammonium salt as a sensitive material to constitute an adenosine diphosphate sensor of a liquid film type electrode. CONSTITUTION:The bicyclo di-ammonium salt expressed by formula L and formula II is used as the sensitive material. In the formula, R, R' denote an alkyl and substd. alkyl of >=3C, X<-> denotes a monovalent anion, Y<--> denotes a divalent anion. For example, the bromide, etc. of 1, 4-diazabicyclo (2, 2, 2) octane are used. Such compd. is impregnated to porous ceramics or polymer to form a liquid film. The electrode is so constituted that both faces of the resultant sensitive film contact respectively with an internal liquid and measuring liquid to obtain the sensor. Since the above-mentioned sensitive material is used, the sensitive material is selectively sensitive with the adenosine diphosphate film and the accurate measurement is made possible. |
