摘要

本文以同一批一价

201

Tl和三价

201

Tl为供试品，采用醋酸纤维薄膜电泳、纸电泳、预饱和层析及非饱和层析等不同方法进行比较，发现上述方法均能将氯化铊中一价铊和三价铊分离，且当

201

Tl中含少量三价铊时，测得一价供试品中一价铊（

201

Tl）分别为99.92%（

0.06%）、99.75%（

0.02%）、99.87%（

0.09%）和99.84%（

0.09%），数值接近。但是，当以三价铊（

201

Tl）作为供试品时，各方法测得的三价铊（

201

Tl）含量分别为26.83%（

29.82%）、19.06%（

40.69%）、90.88%（

0.53%）和15.65% （

35.90%）。实验表明，四个方法测定三价铊的结果很不一致。采用Na

HPO

-丙酮（10：90）为溶剂、并在层析前预饱和15分钟、再上行层析的方法，能有效地测出供试品中三价

201

Tl，而且误差小、重复性理想。为此，上述方法作为

201

TlCl放射化学纯度的测定方法是适宜的。
