| Abstract: | 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. |
