Potentiometric Polymeric Film Sensors Based on 5,10,15-tris(4-aminophenyl)‎ Porphyrinates of Co(II)‎ and Cu(II)‎ for Analysis of Biological Liquids

الملخص EN

Novel carbonate-selective potentiometric sensors based on 5,10,15-tris(4-aminophenyl)-20-phenyl porphyrinates of Cu(II) and Co(II) have been developed.

Ionophore functioning mechanism and possible source of carbonate sensitivity have been evolved.

Potentiometric properties of Co(II)- and Cu(II)TATPP-based sensors were compared with common carbonate-ISEs containing trifluoroacetophenone derivatives.

The analytical utility of newly developed sensors has been demonstrated by measuring the bicarbonate content in human blood plasma.
