【摘要】 用傅氏反应合成了2-对溴苯亚砜（PBSO）,鉴定了合成产物的结构。用反相纸色谱法考察了PBSO和2-对苯基亚砜（DPSO）在HCl和HNO₃介质中对40余种离子的举取行为。比较了DPSO、PTSO（2-对甲苯基亚砜）、PIPSO（2-对异丙苯基亚砜）和PBSO对Au（Ⅲ）的萃取能力。分别以DPSO、PBSO和PTSO为固定相,用反相纸色谱法分离了Au-Pd-Os-Ru;Au-Pt-Pd;Au-Tl;Sb-Bi;Ca-Ba;Sn（Ⅱ）-Sn（Ⅳ）等混合离子。更多还原

【Abstract】 Di-p-bromophenyl sulphoxide （PBSO） has been synthesized by Friedel-Crafts reaction and its structure has been characterized. The extraction power of di-phenyl sulphoxide （DPSO） and PBSO for more than 40 metal ions both in HCl and HNO₃ media was studied and the extraction ability of individual DPSO, PTSO, PBSO and PIPSO （di-p-isopropyl phenyl sulphoxide） for Au（Ⅲ） has been systematically compared and discussed. The data show that, DPSO, PBSO or PTSO can be used as a stationary phase in reversed phase paper chromatography to separate some metal ion mixtures, such as Au-Pd-Os-Ru; Au-Pd-Pt; Au-Tl; Sb-Bi; Ca-Ba and Sn（Ⅱ）-Sn（Ⅳ）.更多还原
