研究盐类对多环芳烃溶解度的影响,不仅涉及盐效应各种理论的研究,而且在化工分离、环境治理上也有重要的实际意义。本文研究了25℃下7种多环芳烃在NaCl水溶液中的活度系数和盐析常数。计算并比较了萘和联苯的盐析常数以及5种多环芳烃在被正辛醇饱和的NaCl水溶液中的活度系数和盐析常数。
Studying the influence of salt on the solubility of PAHs not only involves the study of various theories of salt effect, but also has important practical significance in chemical separation and environmental treatment. In this paper, the activity coefficients and salting-out constants of seven PAHs in NaCl solution at 25 ℃ were studied. The salting-out constants of naphthalene and biphenyl and the activity coefficients and salting-out constants of five PAHs in NaCl aqueous solution saturated with n-octanol were calculated and compared.
