| Abstract: | A method for the determination of lead in stibium concentrates by flame atomic absorption spectrometry has been described in this paper.The method of sample preparation and the interference elements have been studied.The sample is dissolved with HCl-HNO3-HBr,the addition of tartaric acid can depress the hydrolysis of stibium and dissolved sample are analyzed by airacetylene flame atomic absorption spectrometry.The relative standard deviation is less than 1%.The advantages of this method are less interferences,better accuracy and more rapid or simple.The lead in stibium concentrates has been determined by using the method with satisfactory results. |
