Surfactant Enhanced Chromium Removal Using a Silica Gel Column
A simple and rapid method is proposed for the removal of chromium based on its adsorption as an ion pair with Cetyl Trimethyl Ammonium Bromide (CTABr) on a silica gel colurnn. The surfactant (CTABr) is bonded to chromate by electrostatic force of attraction and the resulting ion-association complex...

| description | A simple and rapid method is proposed for the removal of chromium based on its adsorption as an ion pair with Cetyl Trimethyl Ammonium Bromide (CTABr) on a silica gel colurnn. The surfactant (CTABr) is bonded to chromate by electrostatic force of attraction and the resulting ion-association complex is held on a silica gel column. The resulting solution from the column is analyzed for chromium by the standard diphenyl carbazide spectrophotometric procedure. The method has been applied successfully to study the recovery of chromium in various synthetic mixtures. |
