Abstract

The Chromatographic behaviour of scandium, yttrium, the rare earths, thorium and uranium(VI) in dioxan-hydrochloric acid and dioxan-nitric acid media on a plain cellulose thin layer has been investigated. The following separations are possible: scandium-yttrium-lanthanum, scandium-samarium-thorium, scandium-lanthanum-lutetium, yttrium-lanthanum-thorium, and lutetium-thorium-uranium(VI) with dioxan-12M hydrochloric acid (7:3) and scandium-samarium-thorium, scandium-yttrium-uranium(VI), lutetium-thorium, and scandium-lanthanum-thorium with dioxan-14M nitric acid (7:3). A single chromogenic spray (Arsenazo III) has been used for the detection of all the metal ions studied.

摘要

在纤维素薄层上，研究了钪、钇、稀土元素、钍和铀(VI)在二氧六环-盐酸和二氧六环-硝酸介质中的色谱行为。可以实现以下分离：二氧六环-12M 盐酸（7:3）中的钪-钇-镧、钪-钐-钍、钪-镧-镥、钇-镧-钍和二氧六环-14M 硝酸（7:3）中的镥-钍-铀(VI)，以及单一显色剂（偶氮 III）用于检测所有研究的金属离子。
