| Abstract: | OBJECTIVE:To establish a FAAS method for determination of the content of Li in Lithium carbonate tablets.METHODS:The wavelength for determination was at 670.8nm,the electric current of the light was 12.0mA,the slit-width was 0.4nm,the flow rate of burning gas was 2.2L·min-1 and the flow rate of gas to help burn was 15.0L·min-1.RESULTS:The good linear relation was determined as 0.1～1.0mg·L-1 by FAAS with a regression coefficient rate of 0.9999.The average recovery was 99.12%(RSD=0.5%,n=9).CONCLUSION:The method is simple,accurate and sensitive,and can effectively control the quality of Lithium carbonate tablets. |
