| Abstract: |
| Samples of handmade paper was pretreated by microwave assisted digestion, and the contents of As, Pb, Cr, Ni, Sb and Cd in the handmade paper were determined by ICP-MS. Kinetic energy discrimination (KED) were used to overcome disturbance of ions,such as ArCl. The parameters of the test methods were optimized seriously, including RPq and affects of different Neb gas flow rate. Detection limits of the 6 elements were in the ranges of 0.003 mg.kg-1~0.02 mg.kg-1, 3.0mg.kg-1 and 7.0 mg.kg-1 mix standard solution were added in the samples respectively. Values of recovery and RSD’s were found in the range of 88.9%~107.3% and 1.7%~2.6%. As, Pb, Cr, Ni and Sb, were detected in some of the samples. The method is fast, accurate and has a low detection limit. It is suitable for determination of impurity metal ions in handmade paper |
