Abstract

A liquid membrane-based anion-selective electrode for hydrogen sulfite has been developed using a guanidinium ionophore in a poly(vinyl chloride) membrane. At pH 6.00, a logarithmic response to hydrogen sulfite in the range 5.0 × 10⁻⁵ to 0.500 M is observed with a detection limit of 3.9 (±0.3) × 10⁻⁵ M (n = 6). The electrode demonstrated minimal response to other anions, with perchlorate (3) and salicylate (4) being the two strongest interferents. ¹H-NMR complexation was used to study the interaction between hydrogen sulfite and the ionophore in this novel 5 sensor.
