摘要
文章在高氯酸介质中研究了正-戊基己基亚砜(n-PHSO)对Hg(II)的萃取行为,用斜率法确定萃合物的组成是Hg(ClO4)2·(n-PHSO)2,求得了平衡常数。考察了酸度和稀释剂对n-PHSO萃取Hg(II)的影响,并比较了正-戊基己基亚砜(n-PHSO)、正-丁基辛基亚砜(n-BOSO)、正-己基环己烷亚砜(n-HCHSO)、正-丁基戊基亚砜(n-BPSO)、二苯亚砜(BPSO)等几种不对称亚砜对Hg(II)萃取能力的大小。
The extraction behavior of mercury(II) by n-amylhexyl sulfoxide(n-PHSO) in perchloric acid medium has been studied. The composition of the extracted complex was determined by the slope method as Hg(ClO_4)_2·(n-PHSO)_2. The extraction equilibrium constant was calculated to 2.29. The effects of acid and solvent on extraction of mercury(II) with n-PHSO were investigated. Moreover, the extraction ability of mercury(II) with different unsymmetrical sulfoxides has been compared with each other.
