| Abstract: | s:By theoretical analysis and experimental data comparison, this paper notifies that the error in FAAS analysis for the exploitation of salt-lake resources is formed in dilution stage, detection stage and calculation stage, and that it is mainly determined by the combination of the dilution factor, spectral interference, ionization interference, and the calculation method. In order to reduce the error to a bearable degree for the development of chemical processes, the author suggests a best combination of the three stages and offers a solution in the calculation process in the form of excel spreadsheet, with the supporting VBA code given. |
