ATS was characterized by elemental analyses, FTIR, MS and 1H-NMR.The best performance was obtained for the membrane of composition (ATS): PVC: DOS in the ratio 1:33:66 wt %. The sensor shows a linear potential response for Ag+ over a wide concentration range 6.0 x 10-8 -1.0 x 10-1 M and detection limit 4.36 x10-8 with Nernstian slope (57.93 mV decade-1 of activity) between a wide pH range (3.0-10) and a fast response time of 10s. The selectivity coefficient values were calculated with separate solution method, which indicate good selectivity of Ag+ ion. The sensor has a lifetime of five weeks and could be used as an indicator electrode in the potentiometric titration of Ag+ vs. stander solution of NaCl and in the estimation of Ag+ in photographic solutions and medical X-ray samples.}, keywords = {Poly vinyl chloride (PVC),N-(2-acetylthiophene) salicylideneimine (ATS),Silver selective sensor and Nernstian slope}, url = {https://ejchem.journals.ekb.eg/article_1546.html}, eprint = {https://ejchem.journals.ekb.eg/article_1546_bd761077bb832da1bbe75376b5c93a70.pdf} }
