Preliminary results of a quick, simple method of detecting antimony in water samples

摘要

Preliminary results of development of a direct and fast method of determination of antimony in samples of tap water using GFAAS are presented. The found levels of antimony were lower than permitted for human consumption. A mixture of Pd and Mg(NO3)2 (concentrations in the injected solution: 8.6 μg mL~(-1) and 5.8 μg mL~(-1) respectively) was used as the chemical modifier. The pyrolysis and atomization temperatures were 1000 and 1700℃, respectively and the mean analytical recovery 98.2%.
