摘要： A synergistic extractant combination consisting of di(2-ethylhexyl) phosphoric acid (D2EHPA) and dibutyl butyl phosphonate (DBBP) in kerosene is employed in a two-cycle separation process for the recovery of uranium from wet-process phosphoric acid. The addition of the sulfuric acid and water scrubbing steps for the recycled extractant provides no disadvantages with respect to the comtamination and dilution by the ammonium ion and water to the phosphoric acid and also no precipitation occurs in the second cycle extraction step. The advantages of this process are lower chemical cost, higher product purity and better phase separation in comparison with the previous process.

摘要： The present invention relates to a retaining structure for securing at least one expansion card (such as a Peripheral Component Interconnect, PCI card) on a motherboard. The retaining structure includes a frame member and a handle. The frame member has a main body, and the main body has at least one outer fixing portion and an inner fixing portion. The main body has a top piece and a connecting piece. The connecting piece is arranged away from the outer fixing portion and connected to the inner fixing portion. The handle is connected to the connecting piece. Upon mounting of the retaining structure, the distance between the handle and a base plate of a housing is less than the distance between the top piece and the base plate of the housing. This retaining structure may be easily dismounted in restricted space internal of the housing.
