Abstract: An extensive study has been made for the determination of silver (Ag) and cadmium (Cd) in soil and sediment samples using different decomposition procedures. A simple and rapid method has been developed for the accurate determination of Ag and Cd at ppb levels by graphite furnace atomic absorption spectrometry (GFAAS). In the present study,-200 mesh size samples were digested in a 100-mL glass beaker using 1:1 HNO 3 for measurement of Ag and Cd by GFAAS. A bulk calibration standard of 20 ppb of Ag and 10 ppb o…
