Method of extracting domoic acid by selective adsorption using a halogenated carboxylic acid derivative

Method of extracting domoic acid by selective adsorption using a halogenated carboxylic acid derivative

Domoic acid is selectively bound by an adsorbent which comprises units derived from one or more halogenated carboxylic acids (preferably having an alpha-trihalomethyl group) or derivatives thereof. The adsorbent may be a polymer, or a solid support onto which the carboxylic acid, derivative or polym...

description Domoic acid is selectively bound by an adsorbent which comprises units derived from one or more halogenated carboxylic acids (preferably having an alpha-trihalomethyl group) or derivatives thereof. The adsorbent may be a polymer, or a solid support onto which the carboxylic acid, derivative or polymer has been grafted. The preferenced acid is 2-trifluoromethyl acrylic acid. Domoic acid can be selectively bound from a mixture (e.g. seafood extract, seawater or urine) in the presence of potential interferents such as aminoacids, and recovered using an eluant comprising an organic acid.
