[Determination of azlocillin in the air]

A method for determination of air-borne azlocillin in production areas was developed. The method is based on redox reaction proceeding with reduction of the molybdenum blue heteropolycomplex. The reaction involves the antibiotic preliminarily hydrolyzed by alkali with heating. The blue solutions are photometered at 750 nm. The detection limit in the assay sample volume is 0.005 mg. The method may be useful in development of maximum permissible concentration of azlocillin and its control in ambient air of production areas.
