Research on Germanium Extraction from High-concentration H_2SO_4 Solution with HBL101 AITranslate
Abstract AITranslate
Based on the disadvantages of existing germanium extractants,germanium extraction in high-concentration sulfuric acid medium with HBL101was tested.The effects of feed acidity,extractant concentration,time,phase ratio and temperature on the extraction and stripping of germanium were investigated.The extraction and stripping isotherms were plotted.The results show that with 15%（volume fraction）HBL101 and sulphonated kerosene as extractant,the extraction rate of germanium reaches 98.32% in four-stage counter current extraction with O/A ratio of 1∶1 under the optimum conditions.The germanium in loaded organic phase can be stripped using 150g/L NaOH solution and the stripping rate is above 98% in six-stage counter current stripping with O/A ratio of 8∶1.
