PRODUCT DESCRIPTION
ZGA353YT is a macroporous, strongly basic, polystyrene-based anion exchange resin with quaternary amine groups. Its unique macroporous structure provides high capacity and excellent physical and chemical stability. It is primarily used for concentrating and purifying uranium mine wastewater, concentrating and purifying thorium, plutonium, and uranium in the nuclear industry, and recovering vanadium from industrial wastewater in the ammonia industry. It also removes zinc from nickel electroplating solutions.
FEATURES AND ADVANTAGES
● PARTICLE SIZE RANGE 95% of all granules are within the specified range, resulting in lower pressure drop and improved kinetics.
● HIGH PHYSICAL STABILITY More than 90% sphericity combined with high crushing strength and uniform particle size provide greater resistance to mechanical, thermal or osmotic stress.
