Effects of Cobalt Chloride on Determination of Cadmium in Radix aucklandiae by Hydride Generation-Atomic Fluorescence Spectrometry

Abstract:

The cadmium in the Radix aucklandiae was determined by hydride generation-atomic fluorescence spectrometry after the Radix aucklandiae was treated by high pressure digestion. The effect of cobalt chloride to determination of cadmium by atomic fluorescence spectrometry was studied in this paper. The linear relationship was best when the concentration of cadmium standard solution at 0-10ug/L. The linear equation of standard curve was If=290.50×C+19.06. R= 0.9996,while the detection limits was 0.49ng/L,with a relative standard deviation of 0.37% .The cadmium content in the Radix aucklandiae was 56.8-72.3µg/kg with a recovery range of 81.6%-87.2%.
