| Abstract: | Through pyrolysis, Hg and pyrolytic vapor will be reliefed from organic samples. Regarding NaOH and Na2O2 as absorbent, eliminating disturb of acid and reduction gas, covering soil to lessen the burning period, eliminating disturb of smoke and gasoloid, and using Hg collection pipe to absorp Hg, thus, Hg content in organic samples can be measured. It is very quick, easy and suitable in geological measurement. |
| Keywords: | Atomic absorption organic sample Hg measurement |
