| objective:Establish an analysis method of microwave digestion and Tl(metallic toxicants)in bones standard-addition method ICP/AES determination.mothods: Take 0.2g bones power in ptfe digestion tube, add to 3mL HNO3 and 0.5 mL H２O2 ,carried on microwave digestion. Fixed the capacity to 10.0 mL using 2% HNO3 after cooling. Standard -addition method used in the quantitative analysis by ICP/AES. results: recovery is 99.4% ,detection limit is 5.1 ng/g,The linear range of determination was 5～500ng/mL.conclusion.: This method is easy to operate, high recovery, low detection limit, multielement determination simultaneously.The determined results are reliable. |
