| Abstract: | Extraction process based on reversible chemical complexation has high capacity and high selectivity for dilute polar organic solution. In this paper,the experiments have been carried out for extraction of phenol with TBP (in kerosene) from dilute solution. FTIR analysis of organic samples loaded shows that solvent TBP forms complexes with phenol through hydrogen-bond. The structure of TBP complex with phenol has been determined. Extraction equilibrium and cross-current flow experiment have been carried out for a treatment of phenolic industrial effluents by TBP (in kerosene). In order to meet the demanded disposal standard, a new mixed extractant have been developed. |
