| Abstract: |
| atmospheric fallout interference on the determination of arsenic in traditional methods, this paper aimed at the complexity of the atmospheric fallout samples, the samples with hydrochloric acid, nitric acid and perchloric acid on the heating plate heat dispelling, effectively eliminate the influence of a large number of organic matter to the measurement result, for atmospheric fallout research provide a more accurate testing data. This method can effectively eliminate the matrix interference, analysis the cost is low, the determination of high precision and good accuracy, the relative standard deviation (RSD) was less than 2.0%, sample standard addition recovery rate is higher than 90%. |
