A new PVC membrane sensor is described as a potentiometric sensor for amiloride. The
sensor having amiloride–sodium tetraphenyl phthalate (ion-pair) as an electroactive
material and dibutyl phthalate (DBP) as an anion excluder in PVC matrix in the percentage
ratio of 4: 66: 30 (ion-pair: DBP: PVC)(w/w). The membrane sensor exhibits suitable
response to amiloride in a concentration range of 1.0× 10− 2 to 1.0× 10− 6molL− 1 with a
limit of detection of 9.9× 10− 7molL− 1. The slope of the system was− 54.3±1.0 mVdecade ...
