响应曲面法优化超声协同活化剂浸出高硅低锗氧化锌烟尘研究
Optimization of Ultrasound-Assisted Activator Leaching Technology of High-Silicon and Low-Germanium Zinc Oxide Dust by Response Surface Method
摘要
Abstract
In order to maximize the extraction efficiency of zinc and germanium from high-silicon and low-germanium zinc oxide dust(ZOD),the ultrasonic enhanced leaching process assisted by sodium dodecyl sulfate(C12 H25SO3Na)was constructed and optimized by response surface method(RSM),and the accurate prediction model of zinc and germanium leaching rate was established.The results show that on the basis of single factor test,the optimal leaching conditions determined by RSM are leaching temperature of 70 ℃,liquid volume to solid mass ratio of 8 mL/1 g and initial acid mass concentration of 160 g/L.The leaching rates of zinc and germanium can reach 96.94％and 85.41％,respectively.C12H25SO3Na plays a key role as a silica gel inhibitor in the leaching process,effectively preventing the polymerization of silicon ions into silica gel,and this effect is more significant under the combined ultrasonic treatment,reflecting the synergistic benefit between temperature,ultrasound and C12H25SO3Na.The research results provide an efficient recovery strategy for the resource utilization of high-silicon and low-germanium zinc oxide dust,and provide an important technical reference for the recovery of other high silicon waste.关键词
