“…It is known that lipophilic salts not only reduce the membrane resistance, but also enhance the response behavior and selectivity, and reduce interferences from sample anions. 24,25 The presence of lipophilic ionic sites is beneficial for both neutral carrier and charged carrier-based ion-selective electrodes. 26,27 Neutral carrier based cation-selective electrodes require lipophilic ionic sites with a charge sign opposite to that of the primary ion for obtaining Nernstian responses.…”

Foi estudada a resposta potenciométrica do eletrodo de salicilato com o complexo (1,8-diamino-3,6-dioxaoctano) de níquel (II). O complexo 1,8-diamino-3,6-dioxaoctano de níquel (II) [Ni(DADOO)] foi suportado em uma membrana contendo policloreto de vinila (PVC), um plastificante e um aditivo. A influência de diversas variáveis foi investigada e a resposta e a seletividade potenciométrica do eletrodo foram otimizadas. O eletrodo de membrana resultante incorpora 29% de PVC, 63% dioctilftalato (DOP) como plastificante, 2% de cloreto de metiltrioctilamônio (MTOAC) como aditivo catiônico e 6% do ionóforo carregador (m/m). Demonstrou uma resposta de Nernstiana de -59,5 ± 1,0 mV por década para o intervalo de concentração do salicilato entre 7,0 × 10-7 mol L -1 podendo ser empregado para faixa de pH entre 6,0 e 9,5. Foi aplicado com sucesso à determinação do íon salicilato em amostras reais.The potentiometric response of salicylate electrode based on complex of (1,8-diamino-3,6-dioxaoctane) nickel(II) was studied. The complex of 1,8-diamino-3,6-dioxaoctane nickel(II) [Ni(DADOO)] was used as carrier into plasticized polyvinyl chloride (PVC) membrane. The influence of several variables was investigated in order to optimize the potentiometric response and selectivity of the electrode. The resulting membrane electrode incorporating 29% PVC, 63% dioctylphthalate (DOP) as plasticizer, 2% methyltrioctylammonium chloride ( -7 mol L -1 , and can be used over a wide pH range of 6.0-9.5. It was successfully applied to the determination of salicylate ion in real samples.

“…The sensor gave a good Nernstian response of 58±1 mV per decade for silver ion in the activity range 3.3 × 10 -6 to 3.3 × 10 -2 M Ag + . The limit of detection reached 2.1 × 10 -6 M Ag + and exhibited high selectivity for silver ion against the alkali, alkaline earth and transition metal ions [71]. …”

This review presents a general overview about the development of ion-selective electrodes in Iran during the past decade (1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006). All of the reported ion-selective sensors (for cations, anions and organic species) are cited in this review. Sensors for 39 cations, 12 anions, and 23 organic compounds and drugs have been reported in this reivew. Some of the main group cations (e.g. beryllium) as well as most of the lanthanide ion (i.e., presidium, erbium, lutetium, cerium, neodymium, europium, gadolinium, terbium, dysprosium, holmium, ytterbium, and thulium) sensors have been reported for the first time. It is noticable that the best reported sensors for HPO 4 2-, SO 4 2-, Cl -, ClO 4 -, Br -, and I 3 -have been designed and constructed by the Iranian researchers.
