Determination of Five Metal Elements in Leisure Foods by Incomplete Digestion-Microemulsion Sampling-High Resolution-Continuum Source Graphite Furnace Atomic Absorption Spectrometry
A fast and effective method was developed for the determination of Cu, Al, Cr, Cd and Pb in leisure foods by incomplete digestion-microemulsion sampling-high resolution-continuum source graphite furnace atomic absorption spectrometry. The samples were digested by incomplete digestion and the conditions for forming microemulsion were studied using N-butyl alcohol as an auxiliary emulsifier. The effects of matrix modifier, modifier volume, ashing temperature and atomizing temperature on absorbance and absorpt...
