【 摘 要 】

Chloride selective polymericliquid membrane electrode has been developed by using Bis-(2-ethylhexyl)Sebacate (DOS) as plasticizer and 2-[5-(4-nitrophenyl) furyl]-4,5-diphenylimidazole (FFDFIN) as ionophore. Some parameters of evaluation of the electrodeare presented in this work. The constructed electrode showed fast potentiometricresponse to chloride ion in the concentration range from 10-6to 10-2 mol.dm-3 with Nernstian slope of -63.43± 0.85 mV/decade, response time of 25 seconds and life time of 15 days.
