ABSTRACT
OBJECTIVE:To establish the methods for content determination of lead and cadmium in Achyranthes bidentata from different habitats.METHODS:Graphite furnace atomic absorption spectrometry was applied.RESULTS:There were a good linear relationship between the concentration and absorbance of lead and cadmium.The linear range of lead were 0~80.00 ?g?L-1(r=0.999 6) with recovery of 95%~101%(RSD ranged from 0% to 5.00%,n=10).The linear range of cadmium were 0~7.000 ?g?L-1(r=0.998 2) with recovery of 98%~103%(RSD ranged from 1.00% to 5.00%,n=10).CONCLUSION:The method is simple,accurate,convenient and sensitive and the results are satisfactory.
