An atomic absorption method for the determination of 20 elements in lake sediments after acid digestion
The teflon-lined bomb method for the decomposition of siliceous material is shown to be applicable for the determination of 20 elements in lake sediments. The sediment is digested at 140 °C with a mixture of nitric, perchloric and hydrofluoric acids; this destroys all organic matter as well as the s...

| Zusammenfassung: | The teflon-lined bomb method for the decomposition of siliceous material is shown to be applicable for the determination of 20 elements in lake sediments. The sediment is digested at 140 °C with a mixture of nitric, perchloric and hydrofluoric acids; this destroys all organic matter as well as the silica matrix, and yields complete dissolution of the sediment. Quantitative recovery of 20 trace and major elements is obtained when atomic absorption spectrometry is used to complete the determinations. |
