| Abstract: | A perchloroethylene filter sampling in ambient air by microwave digestion membrane, cadmium, magnesium nitrate as matrix modifier, methods for determination of cadmium by graphite furnace atomic absorption spectrometry. This method has the advantages of sim- ple operation process, saving time, acid consumption, little environmental pollution, the sensitivity and accuracy are greatly improved. When the sampling volume was 6000L, the minimum detectable concentration of cadmium is 0. 0008mg/m^3. |
