本文开展了超声波辅助硫酸锌溶液净化除铜实验,分析了超声波对于锌置换净化溶液除铜强化机理。研究采用金相显微镜、扫描电子显微镜、X射线衍射仪、ImageJ等技术对置换产物层微观形貌和分布进行表征,并用等离子体发射光谱仪对不同净化阶段的溶液进行铜离子浓度分析。结果表明,超声波对于置换法溶液净化除铜的强化作用受其强度的影响。低强度超声波(500W)对界面产物的影响较小;而高强度超声波(2000W)能够显著影响固体产物层微观形貌和分布,强化固体产物层中的扩散过程,产生的热效应还有利于提高置换反应效率。高功率超声波导致类球形小颗粒在锌表面不连续分布,增大了两相接触面积;同时在固体产物层中形成贯通孔,减少溶液在固体产物层中扩散的结构阻力。
