| Abstract: | Chromite is decompositied by sodium peroxide and acidificated byhydrochloric acid, adding the same sample blank to the standard solution to make the same base with the sample.Analysis the chromites of the country standard by this way - Inductively Coupled Plasma-Atomic Emission Spectrometry. The results are consistencies with the standard samples.By this way we can get the results quickly and accurately compared with tiaditional methods. |
