A chromoreactand for the selective detection of HSO3- based on the reversible bisulfite addition reaction in polymer membranes.
A new chromoreactand for the reversible optical detection of bisulfite anion is presented with a sensitivity in the range from 0.1 to 10 mM while no absorbance changes are observed for anions such as sulfate, chloride, phosphate or hydroxide.
