摘要

This paper presents a robust potentiometric solid-contact ion-selective electrode (ISE) for the rapiddetection of bromide ions (Br-) in water samples. The sensing membrane contains poly (vinyl chloride)(PVC), bis(2-ethylhexyl)sebacate (DOS) and ionophore without a lipophilic ion exchanger, andprovides good potential responses for Br- in the range of 0.010 to 1.0 μM. The calibration curvedemonstrates detection limits of 2.0×10-9 mol/L (3σ) for bromide ions. Moreover, compared withpreviously reported Br--selective ISEs, the proposed ISE offers remarkably improved sensitivity for thedetection of bromide and provides better selectivity coefficients for HPO42-, CH3COO-, NO3-, and Cl-.The proposed sensor is successfully applied for the practical determination of Br- in real watersamples.
