摘要：

The partitioning behavior of several aromatic hydrocarbons between N-vinylpyrrolidone/styrene (NVPS) and water is reported. Values of log K(pw), concentration-based polymer-water partition coefficient, in this study are 3.39 +/- 0.04, 3.38 +/- 0.01, and 4.69 +/- 0.02 for toluene, naphthalene, and phenanthrene, respectively, in aqueous NVPS solution. A relationship between log K(pw) and log K(ow), octanol-water partition coefficient, is proposed to extend predictive analysis to other solutes. The high molecular weight (approximation 3.4 million g/mol) and high organic solubilization of NVPS make it attractive for use in organic-contaminated water remediation. Potential applications are briefly discussed.
