Název v původním jazyce

Ion-selective electrodes: polyaniline modification and anion recognition

Popis výsledku v původním jazyce

A novel arrangement for polymeric membranes used in ion-selective electrodes is presented. The surface of a conventional plasticized poly(vinyl chloride) (PVC) membrane was coated with a chemically generated film of a conducting polymer, polyaniline (PANI). The effect of PANI on the anionic potentiometric response of PVC membranes derived from calix[4]pyrrole and tridodecylmethylammonium chloride (TDDMACl) is reported. Five different types of electrodes with the following membrane compositions were studied: (1) PVC/PANI (a reference experiment), (2) PVC +TDDMACl (asanion-exchanger)/PANI, (3) PVC + calix[4]pyrrole (as neutral carrier)/PANI, (4) PVC + calix[4]pyrrole +TDDMACl (uncoated membrane) and (5) PVC + calix[4]pyrrole +TDDMACl/PANI. Hydrophilicityof the uncoated and PANI-coated membrane surfaces was assessed by measurements of water contact angle, ?. In the protonated state, the neat PANI is more hydrophilic, ? =49., than in its deprotonated base form, ? =94.. After surface depos
