摘要	Poly(vinyl chloride) membrane strontium ion-selective electrodes were developed by using three lipophilic diamides containing pyridine ring as ionophores. The relationship between the structure of the ionophores and the performance of these electrodes, as well as the effects of the plasticizers and additives, were investigated. The Sr2+-electrode based on N,N,N',N'-tetracyclohexyl-2,6-pyridine-bis(methyleneoxy acetamide) as neutral carrier, potassium tetrakis (p-chlorophenyl) borate (KTpClPB) as additive, and o-nitrophenyloctyl ether (o-NPOE) as plasticizing solvent. It exhibits excellent properties with a Nernstian slope of 29 mV/pSr(2+) and a linearity range or 2 x 10(-5) to 1 x 10(-2) M at 25 degrees C, K-Sr,Ba(Pot) = 2 x 10(-2). (C) 1998 Elsevier Science B.V.
