摘要
二(2-乙基已基)亚砜(DEHSO)是带支链的烷基亚砜,其溶解性能优于直链烷基亚砜,对铊(Ⅲ)的萃取化学尚来见报道。 本文研究了DEHSO-煤油溶液在盐酸介质中对铊(Ⅲ)的萃取行为。实验结果表明,该萃取反应速率快,萃取率随酸度增大而增大,随Cl^-离子浓度增大而降低;温度升高致使分配比下降,由logD与1/T×10~3对画图得斜率为1.95的直线。
The extraction of thallium (Ⅲ) in various conditions from hydrochloric acid medium with di(2-cthylhcxyl) sulfoxide (DEHSO) in kerosene solution has been studied. The chemical composition of extracted species is determined by the methods of Job's ,saturation capacity, slope ratio, Asmus, molar conductivity and IR spectra. The extraction is found to proceed according to the reaction of
