| titleOfInvention | Measuring ion exchange capacity |
| abstract | Apparatus for measuring ion exchange capacity of a material e.g. a geological sample comprises a Hassler tube 1 and a fluid applicator 2 from an HPLC pump 3. The material may be in the form of a sample core plug 4 supported by the tube 1 and is fed solvent containing cations in a soluble form from the pump 3. The first exchange stage replaces all exchangeable cations from the cation exchange sites with Fe<3+> cations. Then the Fe<3+> cations stripped from the exchange site, are collected in a volumetric flask. This is done by treating the plug with a solvent solution containing Na<+> ions. The quantity of Fe<3+> ions recovered is determined by standard analytical procedures and the mass and porosity of the plug are measured used to calculate the cation exchange capacity (CEC). It is preferred the solvents used are methanol, dichloromethane and a combination of the two. <IMAGE> |
