| Abstract: | Continuous determination of trace amounts of lead,cadmium and nickel in nonmetal materials of imitation jewelries was developed by FAAS with microwave assisted HNO3-HF-HCl digestion.The working parameters and digestive conditions were optimized.The effects of concomitant ions and precisions were studied.The method detection limits were 5.7,0.3 and 3.5 mg/kg for Pb,Cd and Ni,respectively.The practical samples were determined,the RSDs were 1.6%～5.2%(n=6),and the recoveries of the above elements ranged from 86.0% to 105.8%. |
