WebIon-exchange capacity is measured in chemical equivalents of base adsorbed at pH 7. Each clay mineral has a range of exchange capacities because of differences in structure and in chemical composition. The ranges (in milliequivalents per 100 grams) are kaolinite, 3–15; halloysite (2H 2 O), 5–10; halloysite (4H 2 O), 40–50; montmorillonite ...

Web5 mrt. 2024 · In ion exchange chromatography, the support consists of tiny beads to which are attached chemicals possessing a charge. Each charged molecule has a counter-ion. The figure shows the beads (blue) with negatively charged groups (red) attached. In this example, the counter-ion is sodium, which is positively charged. WebIon exchange is a physicochemical reversible interchangeable sorption method where an ion in the solid phase is exchanged by another ion from the solution (Vagliasindi and … residential pole barn homes plans

(Adapted from NEUMANN and FATULA 2009) Synthetic and industrially produced ion exchange resins consist of small, microporous beads that are insoluble in water and organic solvents. The most widely used base-materials are polystyrene and polyacrylate. The diameter of the beads is in the range of 0.3 to 1.3 mm. Common examples of ions that can bind to ion exchangers are: H + ( proton) and OH − ( hydroxide ). Singly charged monatomic (i.e., monovalent) ions like Na +, K +, and Cl −. Doubly charged monatomic (i.e., divalent) ions like Ca 2+ and Mg 2+. Polyatomic inorganic ions like SO2− 4 and PO3− 4.
