Abstract

In the presence of organic compounds, such as EDTA, citric acid or triethanolamine, the absorbance signal of Cd during atomization in a tube of electrographite or covered with pyrolytic graphite appears at a lower temperature than the signal from CdCl<sub>2</sub>. Some of these compounds, e.g. EDTA, eliminate the interfering effect of NaCl and MgCl<sub>2</sub>. With urine, however, addition of these compounds often causes splitting of the single absorbance pulse of Cd or an increase of one of the components of a splitted pulse. Addition of a simple modifier HNO<sub>3</sub> is therefore recommended for analyses of urine using atomization in a tube of electrographite. The evaluation of the cadmium concentration was done from integrated absorbances by the method of standard additions.
