| 摘 要： | 采用氯化铵做浸煮剂,从锶渣中回收氯化锶.通过正交实验及单因素实验分析了锶渣粒径、反应时间、液固质量比、n(NH4Cl)/n(Sr)对锶转化率的影响.研究结果表明,最佳工艺条件为锶渣粒径0.054 mm、反应时间2 h、液固质量比3.3、n(NH4Cl)/n(Sr)为3.8.从锶渣中回收氯化锶的回收率可达96%,转化过程符合分形动力学特征.

| Abstract: | Experimental study of recycling strontium chloride from strontium waste residues was conducted with ammonia chloride as the leaching solvent.The effects of the granule diameter of strontium waste residues,the extraction time,the mass ratio between liquid and solid and the n(NH4Cl)/n(Sr) on the conversation ratio was investigated using orthogonal and single factor experiments.The results show that the optimal strontium conversation condition includes strontium waste residues of 0.054 mm in size,a two-hour ex... |
