ABSTRACT:
A sensing composition for polycarboxylic acids which operates in competitive solvents. The composition includes a receptor and an indicator, both of which are mixed in a solvent. Addition of a polycarboxylic acid to the composition causes a change in the physical properties of the composition. Measurement of the amount of change in solution allows the concentration of polycarboxylic acid to be determined. The sensor is preferably selective for polycarboxylic acids, is sensitive, and may be used to analyze solutions of polycarboxylic acids.
