摘要

本文叙述了一个测定土壤中

216

Po的方法。由于

210

Po的物理性质特异，容易吸附在玻璃容器壁上，在150℃时开始挥发

［1］

，因此，不宜用玻璃杯作容器和在高温熔解样品。而土壤中又含有大量硅酸盐及难溶物质，用一般处理方法很难达到完全溶解。文献［2］报道用铂坩埚熔解土壤，但铂坩埚昂贵，来源不易。本方法用塑料烧杯代替铂坩埚作容器，采用氢氟酸加浓硝酸溶解土壤。全程化学产额为（83.7±0.7）%。

Abstract

This paper introduces a method for determining

210

Po in soil. We adopt concentrated nitric acid and 40% hydrofluoric acid to dissolve the sample.

210

Po is electroplated spontaneously on the nickel disc and measured by α-counter. The total chemical yield is 83.7± 0.7%.
