It was applied to the determination of trace amounts of rare earth and other elements in rice samples. Several influencing factors were investigated in detail, such as drying and vaporization parameters, carrier gas flow rate, volume of vaporization chamber and matrix effects. Under optimal experimental conditions, the detection limits for Mg, Cu, Mn, Cr, Fe, Co, Ni and eight rare earth elements are of the order of 10−9−10−11 g. The detection limits for the rare earth elements tested by the present method are comparable to and, in most instances, exceed those for the GFAAS and conventional pneumatic nebulisation-ICP-AES. A precision with RSD<6% was obtained.
