POTENTIOMETRIC RESPONSE OF POLYMERIC LIQUID MEMBRANES BASED ON QUATERNARY AMMONIUM SALTS FOR NITRATE ION DETERMINATION

Polymeric liquid membranes are prepared using (3-nitro-o-xylene (NOX), tri-butylphosphate (TBP), bis-(2-ethylhexyl) sebacate (DOS), o-nitrophenyloctyl ether (o-NPOE), tris-2-ethylhexylphosphate (TEHP), dioctylphthalate (DOP) and dibutylphthalate (DBP) as plasticizers, and they have been used as sens...
