Patent Title: Binding drugs of abuse
Publication date: 2009
Publication number: US20090298194

Abstract: Drugs of abuse (e.g. cocaine) and related substances are selectively bound by an adsorbent which comprises units derived from carboxylic acids of formula A or B: (A): R.sub.1R.sub.2C(CF.sub.3)--CO.sub.2H; (B): R.sub.3.dbd.C(CF.sub.3)--CO.sub.2H 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. A drug can be selectively bound from a mixture, and recovered using an eluant comprising an organic acid.
