by a new extractant HBL121 was carried out based on the problems in the existing extracting process of gallium from zinc smelting slag in hydrometallurgy,such as complex acidity adjusting step,high...,and the conditions of extractant transformation were researched. The results show that with 40% HBL121 (mass fraction) and 20%(volume fraction) in sulphonated kerosene as extractant,the extraction rate......

solution by predispersed solvent extraction (PDSE) process with extractant (HEHPEHE) and its mixture, including acidic extractant (D2EHPA), alkaline extractant (TOA) and neutral extractant (TBP) were carried out respectively. It is found that the extractant HEHPEHE exhibited high extraction selectivity to chromium(III) from aqueous waste solution. The colloidal liquid aphrons (CLAs) were successfully......
