Purolite C100H is an industrial grade, premium gel, polystyrenic, strong acid cation exchange resin supplied hydrogen form. The principal application is in water demineralisation.
Water softening ion-exchange resins are used to replace the magnesium and calcium ions found in hard water. The resin can be regenerated by washing it with salt (NaCl). The calcium and magnesium ions migrate off the resin, being replaced by sodium ions from the solution until a new equilibrium is reached.
Macroporous polystyrenic resins have pore structures significantly more robust than polystyrenic gel resins that allow macroporous resins to be used as catalysts as well as enable use in non-polar applications unsuitable for gel resins. This results in resins that are more osmotically and oxidatively stable and less prone to mechanical breakdown.
In general, strong acid cation macroporous ion exchange resins often provide higher selectivity than their gel counterparts.
