| Abstract: | A method of the determination of the impurity elements in molybdenum concentrate sample by atomic absorption spectrometry was developed. Under the optimum condition, the recoveries obtained of Cu, Co,Ni,Mg,Ca are in the range of 95.0-106.4 % , the relative standard deviation are both not more than 6.0 %. This method is accurate,quick-acquired and concenient. It is used in the determination of molybdenum concentrate with satisfacetory result. |
