Özet:

 

Silver(I)-selective sensors were prepared from a   solid-state contact polyvinyl chloride (PVC) membrane.   (Z)Z)Z)-2-(2-((3-(2-hydroxyphenyl)-5-(p-tolyl)-1HHH-pyrrol-2-yl)imino)-5-(p-tolyl)-2HHH-pyrrol-3-yl)phenol   was synthesized as an ionophore molecule and embedded in the   silver(I)-selective PVC membrane composition. The optimum membrane   composition was determined as 2.5% ionophore, 61.7%   bis-(2-ethylhexyl)sebacate, 1.0% potassium tetrakis (p-chlorophenyl)   borate, and 34.8% PVC. The developed sensor exhibited a linear potential   change EEE = 67.42 (-log [Ag++^{+}]) +++ 1152.9 and R2R2R^{2} = 0.9960) in the varying   concentration range of 1.0 ××\times  10−1−1^{-1} to 1.0 ××\times  10−5−5^{-5}   mol L−1−1^{-1} silver ions. This sensor shows a detection limit of 7.3 ××\times    10−7−7^{-7} mol L−1−1^{-1}. The proposed sensor showed a good potential change   with high sensitivity even in a wide range of pH values (2.0-11.0). The   proposed sensor had a quick electrochemical response of less than 3 s with   good selectivity and repeatability. The sensor was also   successfully applied in the analysis of real water samples. In real water   samples prepared by standard addition method, recoveries in the range of   82.30%-95.15% were obtained.
