Abstract
A procedure is described for the colorimetric determination of Al in acid digests of plant tissue using catechol violet as the chromogenic reagent. Components of plant tissue digests were examined for interference in the determination of Al using the described procedure. For highest accuracy, Al standards should contain macroelements, microelements, and acid at concentrations generally typical of those present in acid digests of the plant tissue being analyzed. Using the described procedure, recovery of Al added prior to digestion was 99.1% and 97.1% for National Bureau of Standards SRM 1571 (orchard leaves) and SRM 1572 (citrus leaves), respectively.Keywords
