Determination of chloride in drinking and ground water by AlCl molecular absorption spectrometry using graphite furnace atomic absorption spectrometer

The use of high temperature molecular absorption spectrometry for the determination of chloride in drinking and ground water samples is described. The chloride is measured by monitoring the absorbance of vaporised aluminium chloride molecule. The effect of various components commonly present in natural waters were studied and any serious interference was found. The accuracy was assessed by comparing the results obtained using the proposed method with those got by conventional titrimetric method.
