Abstract The fluorometric determination of low levels of chlortetracycline in mixed feeds is based upon the separation of the chlortetracycline on a Decalso ion exchange column after extraction from the feed. The chlortetracycline is eluted from the resin after conversion to isochlortetracycline by hot aqueous sodium carbonate. The isochlortetracycline is measured fluorometrically. Results agree with microbial assays.
