l Character:Colorless or near colorless liquid, light fruity, faintly acid, nontoxic, there is not corrosion property for most steel plastic container.
l Usage:Used for extracting Ni, Co, and rare earth elements of gallium (Ga), molybdenum (Mo), germanium (Ge), thulium (Tm), ytterbium (Yb), lutetium (Lu) etc.
l Description (Patent No. 201410053573.0)
The separation coefficient of DZ-272 is more than 20 times of P507 on same condition, it is applied to high content Ni-Co solution, also does not has extraction ability for calcium (Ca), can re-extract iron on the condition of low content sulfuric acid.
DZ-272 can dissolve with fat diluent and aromatic diluent fully, and the stability is good, water-soluble ability is low.
DZ-272 can extract Ni-Co in the system of sulfuric acid and chloride, also can extract rare earth elements of gallium (Ga), molybdenum (Mo), germanium (Ge), thulium (Tm), ytterbium (Yb), lutetium (Lu) etc.
l Advantage:
1. The effective component of DZ-272 can over 90%, has good extraction ability, high selectivity, low water-soluble ability, easy to be re-extracted.
2. The extraction step of DZ-272 is less, can save a lot of investment on equipment and hand work, will save much more cost.
3. The price of DZ-272 is lower than competitor very much.
