Resumen

ARADA PEREZ, M. DE LOS A  y  YAZDANI-PEDRAM, M. BEHAVIOR OF A POLYMERIC LIQUID MEMBRANE ION- SELECTIVE ELECTRODE FOR CHLORIDE ION. J. Chil. Chem. Soc. [online]. 2013, vol.58, n.4, pp.1957-1958. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072013000400009.

Chloride selective polymeric liquid membrane electrode has been developed by using Bis-(2-ethylhexyl) Sebacate (DOS) as plasticizer and 2-[5-(4-nitrophenyl) furyl]-4,5-diphenyl imidazole (FFDFIN) as ionophore. Some parameters of evaluation of the electrode are presented in this work. The constructed electrode showed fast potentiometric response to chloride ion in the concentration range from 10-6 to 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.

Palabras clave : Chloride ion selective PVC membrane; Ion-selective electrode (ISE); 2-[5-(4-nitrophenyl)furyl] -4,5-diphenyl imidazole.
