11. Substrate dependent methods include traditional soil cultivation, zeoponics, agar, and nutrient-loaded ion exchange resins . 12. Anion exchange resin and is therefore used as the trigger for anion resin regeneration. 13. The most common means for removing water hardness rely on ion-exchange resin or reverse osmosis. 14. Most ion exchange systems are containers of ion exchange resin operated on a cyclic basis. 15. It can be used for ion exchange resins . 16. Acetone is treated with a strong acidic, palladium-doped cation exchange resin under medium pressure of hydrogen. 17. Strongly acidic ion exchange resin is then added. 18. Beads that are negatively charged will be cation exchange resins , as positively charged protein will attracted. 19. Ion exchange : Ion exchange systems use ion exchange resin -or zeolite-packed columns to replace unwanted ions. 20. Insoluble microgranular CMC is used as a cation-exchange resin in ion-exchange chromatography for purification of proteins.
