Název v původním jazyce

Spectrophotometric determination of iron, aluminum, and phosphorus in soil and sediment extracts after their nitric and perchloric acid digestion

Popis výsledku v původním jazyce

Pyrocatechol violet and thiocyanate methods used in the water analysis for spectrophotometric determination of aluminum (AI) 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 Al-heating block as for the total phosphorus (P) analysis 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.
