用偶氮胂Ⅲ测定钍时,钛会引起负误差。当 Th:Ti 为1:10和1:100时,钍的测定误差为5%。关于钛对钍和其它元素反应的影响性质,本文将略加评论。钛形成多核链式结构的倾向性,可以设想为钛和钍离子形成混合络合物或聚集体,以致影响了钍的基本反应。应该指出,钛对钍的影响的复杂性,在钛存在下测定钍时,使结果偏低,并随着时间的增长,
Titanium can cause negative errors when thorium is measured with arsenazo III. When Th: Ti is 1:10 and 1: 100, the measurement error of thorium is 5%. The impact of titanium on thorium and other elements of the nature of the reaction, this article will be slightly comment. The tendency of titanium to form a polynuclear chain structure is thought to form a mixed complex or aggregate of titanium and thorium ions so as to affect the basic reaction of thorium. It should be noted that the complexity of the effect of titanium on thorium, the determination of thorium in the presence of titanium, lowers the result and, as time goes by,
