| titleOfInvention | A kind of assay method of arsenic valence state |
| abstract | The invention discloses the assay method of a kind of arsenic valence state.Including: (1) adds extract in testing sample, after gas release completely to be generated, is cleared up by microwave, is filtered by digestion solution, wash residue with extract, collect cleaning solution, with filtrate, it is mixed constant volume；Testing sample is coal or domestic refuse incineration ash, soil or mud；Extract is H 3 PO 4 Mixed solution with ascorbic acid；(2) trivalent arsenic is separated with pentavalent arsenic；(3) isolated trivalent arsenic and pentavalent arsenic are reduced, obtain arsine gas；(4) arsine gas obtaining the arsenic reduction of different valence state is measured, and obtains trivalent arsenic and the content of pentavalent arsenic in testing sample.The method can realize trivalent arsenic and the lossless extraction of pentavalent arsenic and quickly efficiently separate, the measurement result degree of accuracy is high, and simple to operate, measure and cost of equipment maintenance is low, it is adaptable in the solid waste such as fuel incineration residue, soil or mud, the analysis of arsenic morphology measures. |
