摘要

  • 摘要: 本文研究了硅橡胶膜对不同苯胺类物质的萃取效果, 并结合有机物的结构参数进行分析.结果表明, 苯胺类物质在硅橡胶膜中的萃取过程与其取代基的类型密切相关, —CH3和—NO2 等疏水性基团的存在可以提高苯胺类物质在硅橡胶膜中的萃取率, 但取代基的种类以及位置不同, 会使苯胺类物质在硅橡胶膜中的萃取效果趋于复杂化;从结构参数的角度分析, 苯胺类物质的萃取率主要取决于辛醇/水分配系数(lgP)以及溶解度(S)两个参数;萃取实验的结果显示, 苯胺类物质在硅橡胶膜中的萃取率与辛醇/水分配系数呈现显著正相关(R2为0.940), 与溶解度呈现显著负相关(R2为0.817), 这表明有机物疏水性越强, 越容易在硅橡胶膜内分配;但透过实验的结果显示, 透过率随辛醇/水分配系数的增大呈现先升高后降低的趋势, 当lgP在1附近时, 透过率达到最大值.
    Abstract: The extraction of different anilines by silicone rubber membranes was investigated. The relationship between the extraction efficiency and structural parameters of anilines was analyzed. The results showed that the anilines extraction process in the silicon rubber membrane was closely related to their functional groups. The hydrophobic groups such as —CH3 and —NO2 could increase the extraction efficiency. However, considering different functional groups and position, the extraction effects of silicone rubber membrane on different anilines would become complicated. According to the structural parameters, anilines extraction efficiency depends mainly on the octanol/water partition coefficient (lgP) and solubility (S). Extraction experiments showed a significant positive correlation between extraction extent and lgP (R2 was 0.940), as well as a significant negative correlation between extraction extent and S (R2was 0.817). It suggests that hydrophobic organics dissolved more easily in the silicone rubber membrane. But the permeation experiments showed that the permeability first increased and then decreased with the increase of lgP. When lgP was around 1, the permeability reached the maximum value.
