Applications:
P-350 is a new type of extraction agent with strong extracting ability, high selectivity and portative power. It is also a kind of extraction agent with good chemical stability and irradiation performance.
It does not produce swelling with plastic extraction slot. It is powerful in extracting Uranium, Thorium and Lanthanum in nitric acid. It is also used for separating Uranium from Thorium and purifying for high-grade Lanthanum, Praseodymium and Neodymium.
Package:
The product is package in polypropylene barrel (200 l) weighing 180 kg per barrel.
