摘要
研究了在磁场作用下 ,于盐酸溶液中 ,用乙酰胺 (A10 1)对稀土元素的萃取。讨论了磁场的作用及萃取机理 ,并分析了磁场作用及使萃取率上升的原因。研究结果认为 :在磁场作用下稀土的萃取率稍有升高 ,萃取机理不变。萃取率的上升是因体系物理性质发生变化而造成。磁场作用对分配比的影响与稀土元素的磁矩大小无规律性关系。
ion:The extraction of rare earths by A101 in HCl solution within magnetic field was studied.The principle of extraction was discussed and the effect of magnetic field on extractability was analyzed.The data illustrated the extractability was slightly increased in the magnetic field,which could be explained by the same extraction principle.It is the change of physical properties of system that makes the extractability increase.The magnetic field does not have periodical relationship with the distribution ratio and magnetic length of rare earths.
