Potentiometric Characteristics of Metal(II)- Triethylene tetramine-Acidic Drug Membrane Electrodes

  • Published : 2002.10.01

Abstract

Potentiometric sensors are important and viable devices for use in pharmaceutical analysis. liquid polymeric membrane electrodes for many basic drugs and a few acidic drug were reported. The acidic drug-metal(Ⅱ)-triethylene tetramine ion pair complexes were prepared and used in poly(vinyl chloride) membrane electrodes to analyze anionic drugs such as mefenamic acid and ibuprofen. Metal ion used were Fe2+. Co2+. Ni2+ and Cu2+. Plasticizer used was o-nitrophenyl octyl ether.. (omitted)
