| titleOfInvention | A method of step by step arithmetic vanadium chromium and removing aluminium silicon from alkaline aqueous solution |
| abstract | The present invention provides a kind of from alkaline aqueous solution step by step arithmetic vanadium chromium and the method for removing aluminium silicon, the described method comprises the following steps：Organic carboxylate is added in the alkaline aqueous solution of containing vanadium and chromium aluminium silicon, obtains mixed aqueous solution；Alkyl amine extractant is mixed with organic diluent, obtains mixed organic solvents；Mixed aqueous solution is mixed with mixed organic solvents and is extracted, the system that upper layer and lower layer liquid coexists is obtained, upper layer is the organic phase of aluminium containing vanadium, and lower layer is water phase containing chrome-silicon；Vanadium aluminium organic phase will be contained and carry out the processing of back extraction twice, respectively obtain water phase containing vanadium, phase containing aluminum water and the first upper organic phase；It chrome-silicon water phase will be contained will be mixed with the first upper organic phase and extracted, and obtain organic phase containing chromium and siliceous water phase；It chromium organic phase will be contained will be mixed with back washing agent and will be stripped, and obtain water phase containing chromium and the second upper organic phase.The present invention effectively step by step arithmetic vanadium chromium and can remove aluminium silicon from concentrated alkaline aqueous solution, and technological process is brief, and process costs are low. |
