| Abstract: | In this paper a method for direct determination of chloride by vapour molecular absorption spectrometry is developed Chloride was first oxidized to Cl_2 by a strong oxidizer in a strong acidic solution, The formed Cl, was then introduced into a special cell of an atomic absorption spectrometer,The chloride was determined by measuring the absorbance of Cl_2 vapour at the emission line of 324.7nm of copper hollow cathodic lamp. The detection limit was shown to be 2.0ppm. The method has been satisfactrily employed to analyse practical samples, |
