Abstract A previously reported method for the determination of chromium in plants and biological materials has been simplified. The method, which involves wet digestion, isolation and concentration of chromium by liquid-liquid extraction, and final determination by atomic absorption spectrophotometry, is sensitive to about 20 ng chromium. Recovery studies and analysis of standard materials show that this method is reliable.
