SEPLITE® Monojet™ LSC7100 is a macroporous, weak acidic cationic chelating resin with an iminodiacetate chelating active group.
The iminodiacetic acid functional group is specially developed for selective extraction of metals from waste water or brine of the chlor-alkali industry. It also provides high selectivity for copper recovery from spent liquid or for cobalt and manganese from PTA spent crystallization liquor.
Thanks to its proprietary aminomethylation chemical route, Monojet LSC7100 guarantees extremely low leakage.
Its optimized polymer structure and excellent chemical and physical stability ensure its high performance during operation in both fixed bed columns as well as resin-in-pulp processes.
In operations, Monojet™ LSC7100 demonstrates excellent mechanical strength to osmotic and thermal shock.
