| Abstract: | A method for the determination of lithium in spodumene by flame emission spectrometry was reported in this paper.Samples were digested with HF-HClO4 mixed acid and lithium in the sample solution was determined by emission spectrometry.The results showed that in the 1% HNO3(V/V) media and at the air pressure of 0.3 MPa with acetylene flow rate of 1.2 L/min,100 times of coexistent elements of K,Na,Ca,Ba,Sr did not interfere with determination.The standard addition recovery of the method was 94.0%~106.0% with precision of 1.52%RSD(n=10). |
