Embodiment 1
[0017] Take 100L of alkaline solution containing 8g / L of germanium obtained by absorbing the acid gas produced in the chlorination distillation process of germanium and treating it with the tail gas of the spray tower. In the tank of the anion exchange resin, the alkaline solution is added at a rate of 10 L / min, and the resin absorbs the sodium germanate in the solution to obtain a resin containing germanate ions, and the treated alkaline solution continues to absorb germanium after adding sodium hydroxide. Acidic gas produced in the chlorination distillation process; the resulting resin containing germanate ions is added to 100L of 1mol / L dilute hydrochloric acid to analyze germanium to obtain an acidic solution containing tetravalent germanium ions and the resin after analysis. After the resin is washed with deionized water to prepare for the next germanium adsorption, the washing solution is incorporated into the acidic solution containing tetravalent germanium ions, and 4kg...
Embodiment 2
[0019] Take 150L of alkaline solution containing 9g / L of germanium obtained by absorbing the acid gas produced in the chlorination distillation process of germanium and absorbing the tail gas of the spray tower. In the tank of the anion exchange resin, the alkaline solution is added at a rate of 10 L / min, and the resin absorbs the sodium germanate in the solution to obtain a resin containing germanate ions, and the treated alkaline solution continues to absorb germanium after adding sodium hydroxide. Acidic gas produced in the chlorination distillation process; the obtained resin containing germanate ions is added into 120L of 0.5mol / L dilute sulfuric acid to analyze germanium to obtain an acidic solution containing tetravalent germanium ions and the resin after analysis. After the final resin is washed with deionized water to prepare for the next germanium adsorption, the washing solution is incorporated into the acidic solution containing tetravalent germanium ions, and 5kg o...
Embodiment 3
[0021] Get 100L of alkaline solution containing 0.3g / L of germanium obtained by absorbing the acid gas produced in the chlorination distillation process of germanium through the absorption treatment of the spray tower tail gas, and add the alkaline solution to a 201×7MB weak alkaline solution at room temperature. In the tank of styrene-based anion exchange resin, the adding rate of alkaline solution is 10L / min. The resin adsorbs the sodium germanate in the solution to obtain a resin containing germanate ions, and after adding sodium hydroxide to the treated alkaline solution, continues to absorb the acid gas produced in the chlorination distillation process of germanium; the obtained germanate ion-containing Add the resin in 100L of 1mol / L dilute hydrochloric acid to carry out the analysis of germanium to obtain the acidic solution of tetravalent germanium ions and the resin after analysis. The resin after analysis is washed with deionized water to prepare for the next germaniu...
