A highly selective poly (vinyl chloride)(PVC) membrane electrode based on 1, 8-dibenzyl-1,
3, 6, 8, 10, 13-hexaazacyclotetradecane–Ni (II) as a membrane carrier with unique
selectivity toward thiocyanate is reported. The influence of membrane composition, pH and
foreign anions were investigated. The sensor exhibits a Nernstian response for thiocyanate
over a wide concentration range of 3.3× 10− 6 to 0.10 M, with a slope 58.4±0.3 mV per
decade. The limit of detection is 3.0× 10− 6M SCN−. The sensor has a response time of< ...
