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.

Speed And Accuracy

Abstract A method for determination of lead in blood, urine, and tissue is presented. This procedure combines the selective concentration of lead by, and the elimination of large quantities of alkali metals on, an anion-exchange resin with the speed and accuracy of determination by atomic absorption spectrophotometry.
