The dependence of the extraction distribution ratios on the concentrations of extractant, phenol, acidity and temperature was investigated. By means of the slope method, the composition of the extracted complex was deduced to be C6H5. OPOD, and the related thermodynamic functions were also calculated. The IR and NMR spectra showed the presence of intermolecular hydrogen bonding between phenol and OPOD. The experimental results indicated that OPOD could extract phenol effectively.展开更多

The dependence of the extraction distribution ratios on the concentrations of aqueous nitric acid, extractant, salting-out agent and the temperature was investigated. The constitution of extracted complex was established, and the related thermodynamic functions were calculated.展开更多
