摘要
近年来,硫代磷酸酯萃取分离金属的研究日益增多,人们较多地注意其萃取机理和萃合物组成,而以量子化学计算说明硫代磷酸酯结构与铊(Ⅰ)萃取关系的研究甚少。本文比较了二(2-乙基己基)单硫代磷酸(D_2EHMTPA)、二(2-乙基已基)二硫代磷酸(D2EHDT-PA)]和二(2-乙基已基)磷酸(D_2EHPA)从硫酸介质中对铊(Ⅰ)的萃取行为。
The extraction of thallium(Ⅰ) from sulfuric acid medium with some thiophosphates has been studied in various conditions. The relationships between the structure and the property of extractants have been discussed in terms of the calculated results obtained by EHMO method.
