[Determination of total sulfur in coal by inductively coupled plasma atomic emission spectrometry].
A direct method was reported for the determination of total sulfur in coal by inductively coupled plasma atomic emission spectrometry (ICP-AES). The dissolution conditions of coal samples as well as interference conditions of hydrochloric acid and matrix were studied. The recommended method not only proved to be simple and rapid than traditional gravimetric method but show satisfying precision and accuracy as well. The results of samples are as same as gravimetry. The recoveries are more than 96%, and the relative standard deviation of six samples are less than 3%.
