[Method for the determination of trace Li in serum of cancer patients by tungstate-coated graphite furnace atomic absorption spectrometry].
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)2SO4 as a matrix modifier. The effects of different metal ions and biological matrix were eliminated. The characteristic concentration is 5.53 x 10(-3) microg x mL(-/1)%. The recovery is greater than 93.72%. The relative standard deviation is less than 8.93%.
