The 8-hydroxyquinoline method was modified to measure kinetically labile Al in aqueous soil extracts containing Al-complexing ligands and to measure total soluble Al after removal of fluoride and organic C. Nonlabile Al complexed by F, C, Si, and OH in the original samples is calculated as the difference between total and labile forms. The method measures as little as 100 ng of Al in soil extracts and natural water samples.
