| Abstract: | It is reported that the combination use of the LZ-1200 FIA hydride generator and the WFX-10 atomic absorption spectrophotometer is applied to the determination of mercury in garbage samples. A thorough study is made on the choice of concentration and flow rate of the reaction medium, length of the reaction coil, and the effects of co-existing ions. The proposed method has the special feature of high accuracy and precision, simple and rapid in operation, and low consumption of chemical reagents. The system proves to be satisfactory in practical application. |
