The use of molecular absorption spectrometry for the determination of chloride in inorganic solid samples is described. The chloride is measured by monitoring the absorption of vaporised chlorine molecules. The liberation of chlorine is performed by adding concentrated sulphuric acid containing potassium permanganate. The effects of various components commonly present were studied and no serious interference was found. The accuracy was assessed by comparing the results using the proposed method with those obtained by other methods same as well as by artificial samples.
