Electrothermal atomic-emission spectrometric determination of lithium with a metal-tube atomizer and a matrix
1Department of Industrial Chemistry, Faculty of Engineering, Mie University, Tsu, Mie 514, Japan.
Abstract:
Electrothermal atomic-emission spectrometric determination of lithium with use of a tungsten tube has been investigated. Lanthanum nitrate is used as a matrix modifier to eliminate the interference of Al, Ca, Cu, Fe, K, Mg, Na, Pb and Zn. Lithium in biological samples has been determined by the method. The recovery of lithium in the samples was > 91%.
