Electrothermal atomic absorption spectrophotometry of cadmium in semen.
We describe the electrothermal atomic absorption spectrophotometry of cadmium in rabbit semen collected before and after seven days of subcutaneous administration of 0.5 mg of cadmium per kilogram body weight per day. The analytical technique involves combining an aliquot of an acid-digested semen sample with an equal volume of an (NH4)2HOP4 solution (50 g/L), to allow an increase in charring t...
متن کاملAnalysis of Low Lead and Cadmium Concentrations in Soil Extracts by Graphite Furnace Atomic Absorption Spectrophotometry
An analytical procedure was derived to provide an accurate measurement of low lead (Pb) and cadmium (Cd) concentrations in soil extracts using graphite furnace atomic absorption spectrometry (GFAAS). Based on peak area measurements and with background correction, the use of 2% phosphoric acid as chemical modifier enables the GFAAS to give measurements of Pb and Cd concentration as low as 3 fLg ...

متن کاملDirect determination of lead and cadmium in blood and urine by flameless atomic absorption spectrophotometry.
We describe procedures for direct determination of lead and cadmium in blood and urine by flameless atomic absorption spectrophotometry. Before analysis, the samples are pre-ashed in microboats in an ordinary laboratory oven. In this way, many samples can be prepared and pre-ashed simultaneously. We find the procedures presented in this work to be rapid, accurate, and precise.
