The present study focuses on the advancement of a chloride ion potentiometric sensor that exhibits high selectivity. This employs novel molecule, namely N, N-Ethylene-bis-(Salicylideneaminato) zinc (II), in order to achieve accurate measurements pursuit maintaining clean environment. N′-Ethylenebis( salicylideneaminato) nickel (II) ionophore has been generated as well evaluated using analysis NMR, IR and C, H, N. Subsequently, membranes incorporating (I) were developed utilizing poly(vinyl chloride) (PVC) matrix, with plasticizing solvent mediators including Dioctyl phthalate (DOP), chloronapthalene (CN), Dibutyl (DBP), tri- n -butylphosphate (TBP). Additionally, catalyzed cation discriminator, hexadecyltrimethylammonium bromide (HDTMA) was employed enhance membrane formation. performed better than all other variants. Its composition 5 mg ionophore, 32 PVC, 60 DBP, 3 HDTMA. Notably, exhibited an extended operational range 2.0×10 −6 1.0×10 −1 M, addition Nernstian compliance (58.8 mV/Decade) within pH span 2.3–9.3, impressive response time 19 s. A detection low 1.64×10 attained, indicative its sensitivity. Furthermore, remarkable selectivity for ions, confirmed by coefficient obtained through fixed interference technique (FIM). demonstrated satisfactory three-month shelf life acceptable repeatability. In practical application, effectiveness quantifying ions wastewater samples. work addresses important sustainability issues while contributing improved comprehension underlying concepts self-assembled behavior setting up option generation efficient sensors potential uses photonics microelectronics.
