摘要
铊(Tl)是一种高毒性稀有金属元素,自然界中主要有+1价、+3价化学价态,Tl^+、Tl ^(3+)在性质、毒性等方面均相差较大。以往关于铊的检测方法一般只提及铊,混淆Tl^(3+)和Tl^+。将两种价态铊的测定方法进行分类,并对相应方法进行评价,介绍了Tl^(3+)、Tl^+之间转换常用试剂与方法,展望了铊测定方法的发展趋势。
Thallium（Tl） is a rare metal element which is highly toxic. The element has two dominant redox states,monovalent（ Ⅰ , thallous） and trivalent（ Ⅲ, thallic）, but their properties and toxicity are very different. The most reported detection methods mentioned only thallium, the valence of the element was obscure. In this paper,the classification and summary of Tl3＋ and Tl＋ detection methods are proposed, the corresponding methods are compared and evaluated. The methods of conversion between the two states （Tl3＋ , Tl＋ ） are also introduced. The development trend of the methods for thallium determination is prospected.
