The use of thermally shielded graphite furnaces for the determination of molybdenum in soils and plants by electrothermal atomic adsorption spectrometry






Magyar Kemiai Folyoirat 97(6): 241-245

The use of thermally shielded graphite furnaces for the determination of molybdenum in soils and plants by electrothermal atomic adsorption spectrometry

Soil was extracted with Tamm's solution and plant ash extracted with hydrochloric acid. The use of thermally shielded furnaces prolonged the furnace lifetime and significantly improved the reliability of analytical data.
