摘要
本文根据DBS-偶氮胂与钍的显色反应,提出了矿石中微量钍的测定方法。本法得到的配合物至少可稳定25小时。干扰离子采用TBP分离法,测定的结果满意。
This paper suggests a determination method of trace thorium in ores according to DBS-arsenazo and colour-reaction of thorium. The coordination compounds from the method can be stable for at least 25 hours. The interference ions are separated by the TBP separation method. The results are satisfactory.
