	Article:	FLAME ATOMIC EMISSION QUANTIFICATION OF LITHIUM IN NATURAL WATERS USING THE METHANE�AIR FLAME AS AN ALTERNATIVE EXCITATION SOURCE. Authors: LADISLAU KÉKEDY-NAGY.


	Abstract: The lithium content of some natural waters has been determined by flame atomic emission spectroscopy using the methane-air flame. It was studied the effect of Na, K, Rb, Cs, Mg, Ca, Sr and Ba on the emission of lithium in the conditions of earlier optimized flame and instrumental parameters. The lithium content of some mineral -, well - and seawaters has been quantified using the standard calibration and the standard addition method. The results agree between these two methods.
