摘要
通过热力学的方法,研究了水溶性有机酸对萘的溶解度及迁移性能的影响,结果表明,萘的溶解度和萘由纯水向不同浓度有机酸溶液的迁移能力随着有机酸浓度的增加而增加,但这种趋势并非简单的线性增加,当有机酸浓度超过一定数值后,萘的溶解度会突然增大,迁移趋势会明显增加.这种变化与在稀溶液中形成的水包有机酸笼合物结构有关.
The effect of dissolved organic acids on the solubihty and properties of transfer of naphthalene was studied by using thermodynamic method. The results show that the solubility and the tendency of transfer of naphthalene from water to water organic acid mixtures were increased with the increasing of organic acid concentration. However, this increasing tendency did not exhibit a linear relationship with the increasing of organic acid concentration. It exhibited a sudden change as the concentration of organic acid over a specific value. This change region. can be contributed as the effect of the existence of a clathrate structure of organic acid in the water-rich region.
