摘要：

Using a tungstate coated graphite tube. The sensitivity of Li was significantly increased and trace Li in serum samples was determined by Zeeman graphite AAS with (NH4)(2)SO4 as a matrix modifier. The effects of different metal ions and biological matrix were eliminated. The characteristic concentration is 5.53 X 10(-3) mu g . mL(-1)/1%. The recovery is greater than 93.72 %. The relative standard deviation is less than 8.93 %.
