摘要
用7815从含锗硫酸锌溶液中萃取锗时产生乳化,引起乳化的主要物质是溶液中的Si O_2胶体。通过选择有效絮凝剂明胶,在温度70℃下搅拌反应30 min,常温下静置3 h可使溶液中Si O_2降至50 mg/L以下,避免了乳化。
The emulsification is generated during germanium extracted from germanium-bearing zinc sulfate solution by 7815; the major material caused emulsification is the SiO2 gel in the solution. In order to avoid emulsification, we chose the gelatin with floccnlant ; stirring reaction for 30min. under 70℃, after 3h standing under normal temperature, the SiO2 in the solution can be decreased to under 50mg/L.
