摘要
:NaDDTC能与氯化轻稀土溶液中的Mn2+形成易于滤除的沉淀,用该方法能将溶液中的锰降至02mgL以下,同时,Pb2+等重金属离子也被有效去除。在对除锰效果的影响因素进行研究的基础上,确定了合适的工艺条件。
A new Mn 2+ removing method by using Na DDTC to complex Mn 2+ and forming an insoluble,easily filtered compound,Mn(DDTC) 2,is reported.As the result,Mn content in LRE chloride solutions has been reduced to less than 0.2mg/L,and heavy metal ions (e.g.Pb 2+ ) content also bave been dramatically lowered.Based on the influence factors,suitable treating conditions were determined.
