Amberlite|r IRC-748, ion exchange resin is used as a chelating resin with high affinity for heavy metal cations compared to alkali or alkaline earth metals. It is also utilized in metal-chelation applications. Further, it is used in purification of brine in the chloralkali industry as well as the purification of process streams having trace metals. In addition to this, it is used in the electroplating industry and in the recovery of heavy metals from hydrometallurgical leach streams.
Iminodiaceticacid chelating resin for metals removal. Exhibits high selectivity for Ca, Mg and Sr in chloroalkali brines. Also selectively removes heavy metal cations in the presence of alkali metal ions in process and waste streams.
