ResinTech SIR-600, Cesium/Potassium/Ammonium Selective Cation Resin, 1 Cubic Foot
ResinTech SIR-600 is a sodium/potassium form granular aluminosilicate zeolite. SIR-600 is an inorganic cation exchanger that can also capture certain ions by molecular sieving. ResinTech SIR-600 is particularly selective for cesium, potassium, and ammonium. SIR-600 is intended for removal of radioactive cesium from waste waters that contain moderate levels of sodium and potassium, and for removal of ammonia from water. ResinTech SIR-600 is supplied in the mixed sodium/potassium form.
Features & Benefits
- Removes Cesium, Ammonia, Strontium & Potassium: Selectively removes ions in the presence of hardness and sodium
- Order of Selectivity: Cs>>K>NH4>>Na>>Sr>Ca>Mg
- Physically Stable: Resists oxidative attack and the effects of radiation exposure
- Controlled Granule Size: Large granules provide good physical strength and minimal fines provide low pressure loss
- Controlled Granule Size: Large granules provide good physical strength and minimal fines provide low pressure loss
Applications:
- Ammonia Removal: ResinTech SIR-600 has high affinity for ammonia compared to sodium and moderate affinity compared to potassium. SIR-600 can be used to remove modest concentrations of ammonia from waters with TDS in the potable water range (less than 500 ppm TDS). Regeneration is accomplished with sodium chloride brine in a fashion similar to a water softener. Because the affinity for ammonia is quite large compared to sodium, the regeneration dose required to remove the ammonia from the media is substantial, generally in the range of 20 to 40 lbs per cu. ft.
- Cesium Removal: ResinTech SIR-600 has very high selectivity for cesium over sodium and divalent ions, such as calcium and magnesium. Relative affinity for cesium over common ions found in potable water supplies is typically more than 100 to 1. Cesium is not effectively eluted from SIR-600 by regeneration with brine. Cesium laden SIR-600 is easily stabilized for safe disposal due to its inorganic crystalline structure.
