ResinTech RSM-25 is a sodium form macroporous strong acid cation resin. Its high crosslinking results in very high selectivity for radium on a one-time use basis. It does not contain barium, operates across the pH range, and does not require a minimum sulfate concentration in the raw water. RSM-25 is intended for radium removal from otherwise potable waters that contain modest concentrations of hardness ions such as calcium.
