Description	Pyrocatechol violet and thiocyanate methods used in the water analysis for spectrophotometric determination of aluminum (Al) and iron (Fe), respectively, were modified for the determination of these elements in different types of commonly used extracts of soils and sediments. The extracts were digested with nitric and perchloric acid in an aluminum heating block as for the total phosphorus analysis (Kopácek and Hejzlar, 1995) and aliquots of the digests were analyzed for Al and Fe. Comparison of the spectrophotometric methods with inductively coupled plasma method was demonstrated using (i) oxalate, citrate-dithionite, and pyrophosphate extracts of 25 samples of acid forest soils, and (ii) water, sodium hydroxide, dithionite-bicarbonate, and hydrochloric acid extracts of eight fresh water sediments.
