WebIn practice, weak resins are regenerated with a small excess over the stoichiometric quantity. The typical operating capacity of a weak base anion exchange resin is 70 to 90 % of the total capacity. For weak acid cation resin, operating capacity depends on several parameters, so there is no such simple estimate. WebThe resin was regenerated with 0.35 normal sulfuric acid, at a regeneration ratio of 1.6. The regeneration ratio is a factor expressing the total amount of acid used compared to the theoretical minimum required to displace a desired amount of ions in the resin. ugg boots bailey button gray https://thomasenterprisese.com
