摘要：

A fibre-optic sensor for the determination of carboxylic acids based on fluorescence enhancement of lipophilized fluorescein isologues dissolved in a plasticized poly(vinyl chloride) membrane was developed. With the optimum conditions described, carboxylic acids in sample solutions from 1 to 9 M (formic acid), 0.5 to 10 M (acetic acid), 0.1 to 2.7 M (propionic acid) and 1 x 10(-4) to 1 X 10(-2) M (benzoic acid) can be determined. The response times of the sensor to carboxylic acid are less than 1.5 min. In addition to high reproducibility of the fluorescence signal, the sensor exhibits fair selectivity for carboxylic acids.
