| Abstract: | The paper adopts enlarging sample disposal amount to predispose the sample for determing the content of Zn, Cu, Fe, Mn, Cd, and Pb contained in Vegetative Samples by the method of rare nitric acid moistening--charcoalnization-high fire ashnizatioin, air-ethyne flame directly atomizing agueous solution, deuterium light deducting background absorption atom absorption method. Average rate of recovery: Zn 108 %, Cu 99 %, Fe 118 %, Mn 98 %, Cd 97 %, Pb 98 % CV:Zn 2. 02%, Cu 11. 24%, Fe 12. 41 % Mn 1. 27%, Cd 6. 90%, Pb 7. 03% |
