| Abstract: | This is a method to continuously determine copper,cadmium,lead and zinc concentration in copper and cadmium sediment by FAAS.The sample is digested with acid mixture of HCl-HNO3.Under the determination condition,the recoveries are in the range 97.9%～100.8% and the RSDS of the method are found to be in the range1.59%～14.29%.This method is sensitive when the concentration of Cu,Cd,Pb and Zn is higher than 0.1% respectively. |
