| titleOfInvention | Method for analyzing the composition of chlorine-containing vanadium compounds |
| abstract | The invention relates to the technical field of composition analysis of compounds, and discloses a composition analysis method of a chlorine-containing vanadium compound. The chlorine-containing vanadium compound is hydrolyzed in an acidic aqueous solution to obtain a pale yellow clear and transparent solution. The form of ions is dissolved in the aqueous solution, and then the pH is adjusted to a suitable range. Finally, the vanadium ions and chloride ions in the catalyst hydrolyzed solution are titrated with the standard solution of ferrous ammonium sulfate and the standard solution of silver nitrate, and then the accurate chlorine-containing solution can be obtained. The mass fraction of vanadium element and chlorine element in the vanadium compound can accurately analyze the composition of the chlorine-containing vanadium compound. The method is fast, simple, accurate and reliable. |
