Abstract
The new economic method of the direct atomic absorption analysis of the soils as suspensions (~50 mg/ml) is offered. It is based on the double-stage probe atomization which is carried out by means of an original robotized accessory ATZOND-1 to a commercial graphite furnace. It is possible to remove matrix interferences, to use rather representative sample weight of the soil (up to 12 mg), to do without chemical preparation and special calibration standards. The limits of determination in the dry soil for Pb – 0.002, Cd – 0.1, Se –10, Au – 3 mg/kg. It is sufficient for maximum allowable concentrations control and gold content in the rock. Sensitivity adjustment for measurement of Zn, Si, Al and Fe concentrations which contents reaches tens percent is provided. Validation is checked using soil reference materials SP-1, SP-2 and SP-3, S r < 5 %.
