Hang a large separatory funnel above the level of your column, with a tygon tube running from the outlet of the funnel to the outlet of your column. You can adjust the flow rate by adjusting the height of the funnel relative to the top of the column.
WebIon exchange is a method widely used in household filters to produce soft water for the benefit of laundry detergents, soaps, and water heaters. This is accomplished by exchanging divalent cations (such as calcium Ca 2+ and magnesium Mg 2+) with highly soluble monovalent cations (e.g., Na + or H +) (see water softening ). WebIon exchange describes a myriad of terms, for example the ion exchange process, the ion exchange phenomenon, and the unit process of ion exchange. It is referred to as both an adsorption process and a sorption process. However, ion exchange is most often de ned as the reversible exchange of ions between a solid and a liquid in which there
Web12 aug. 2024 · Ion regeneration is the removal of the ions that block or plug the internal exchange sites on resins; it includes the following three main steps: backwashing, regeneration and rinsing. The regeneration process is capable of restoring only 60–80% of the resin capacity, as some ions and hardness are retained on the resins.
