Abstract
In the present study, a novel electrode based on 2,9-dihydroxy-1,10-diphenoxy-4,7-dithiadecane (DHDPDTD) that is selective to cerium (III) cations was evaluated electrochemically, and a Nerenstian slope (19.3±1mVdecade−1) over a concentration range of 1.0×10−8–1.0×10−1M and a detection limit of 2.1×10−9M were observed. The proposed electrochemical sensor displayed a rapid response time of 10s, improved selectivity towards Ce (III) cations in the presence of alkali, alkaline earth, transition and heavy metal cations, and could be used in a pH range of 5.0–8.0. Additionally, the proposed sensor was used as an indicator in the potentiometric titration of fluoride and the determination of F− ions in real samples
