| Abstract: | Different determination conditions of trace selenium in Se-rich tea were studied.The results of the experiment show that trace selenium can be leached out by microwave digestion method,HNO3-HCLO4 microwave digestion and Aisska sinter method.However,HNO3-HClO4 microwave digestion method is simplest and suitable in daily analysis.The determination conditions of trace selenium were optimized.The precision and accuracy meet the requirement of trace analysis and have achieved satisfactory results from the users. |
