| Abstract: |
| Copper–steel clad plates for bearings was digested in nitric acid and hydrochloric acid, with Rh as internal standard, using inductively coupled plasma atomic emission spectroscopy (ICP-AES) for determining the intensity of characteristic line of elements to be measured in specimen solution.The contents of La and Ce in specimen were calculated by standard curve method.The precisions of 1 # and 2# copper–steel clad plates for bearings ( RSD ) were in the rate of 0.98% ~ 1.08%,and the recoveries rate were between 97.0% and 104.6%.So the method is accurate and reliable. |
