WebNov 1, 2010 · Upward curvature (Figure 1b) when observed in flame AAS is almost invariably caused by chemical interference. The analytes are usually Group 1 or 2 lanthanide elements. The most common cause of upward curvature, particularly for Group 1 metals, is a special form of chemical interference: par-tial ionization. The atoms are … WebAug 1, 2006 · This makes its analysis by flame atomic absorption spectroscopy (FAAS) more subtle than the analysis of other alkaline metals such as Na and K. In most FAAS method manuals, little interference was addressed for lithium, and the addi- tion of potassium or cesium deionization buffers was deemed adequate for determining lithium … chernobyl disaster tours
