Abstract

The paper reports the utilization of phosphate, silicate, and sulfate chemical inhibition effects in magnesium atomic absorption spectrometry for the purpose of determination of these anions. The variables found to be of greatest significance in the inhibition processes were flame temperature and solution stoichiometry. The procedure termed 'atomic absorption inhibition titration' (AAIT) was developed. It provides useful, new determination methods for single anions and also for simultaneous determination of phosphate, silicate, and sulfate in a single sample. The methods have been evaluated and applied to water and waste water samples. (Booth-EPA)
