Fiber-Optic Sensor with a Dye-Modified Chitosan/Poly(vinyl alcohol) Cladding for the Determination of Organic Acids

Organic acids in aqueous solution were determined with a fiber-optic sensor having a chitosan/poly(vinyl alcohol) cladding. Interference from ethanol could be reduced by controlling the crosslinking of the cladding with glutaraldehyde and by modifying the cladding with 5′, 5"-dibromopyrogallols...
