Publisher: | Pak. J. Anal. Environ. Chem. | Abstract: | In this article, chromium(VI) extraction properties of two azocalix[4]arene based receptors (L4 and L6) are reported. A preliminary evaluation of the binding efficiencies of p-substituted azocalix[4]arene derivatives L4 and L6 was carried out by solvent extraction of Na-dichromate from aqueous solution into dichloromethane at different pH. It was observed that the new compounds are effective extractants for transferring the HCr2O7 -/Cr2O7 2- anions at low pH. The binding ability of these compounds toward HCr2O7 -/Cr2O7 2- anions depends upon Na+ extraction. | URI: | https://hdl.handle.net/11499/28011 | ISSN: | 1996-918X |
