BACKGROUND In this study, the ion‐selective electrode (ISE) based on ion‐imprinted polymer (IIP) for the determination of phosphate has been described. For selective recognition of IIP, phosphate (analyte–template), chitosan and N ‐(2‐aminoethyl)‐3‐aminopropyl‐trimethoxysilan (AAPTS) (functional monomers), ephychlorohydrin and tetraethoxysilicate (TEOS) (cross‐linking agents) were used. RESULTS The electrode was prepared using the IIP. The IIP‐1‐, IIP‐2‐ and IIP‐3‐based membranes showed a detection limit of 7.6 × 10 −6 , 5.1 × 10 −6 and 2.5.10 −7 mol L −1 , respectively. Attractive features of these IIP‐based ion‐selective electrodes are a rather low detection limit and high selectivity compared with other phosphate molecules. CONCLUSION The proposed method has been applied successfully to analyze phosphate in household waste samples with recoveries of ≥90%. © 2021 Society of Chemical Industry (SCI).
