摘要： The present invention disclosures a preparation method for a coated lithium ion sieve, the method comprises: S01: calcining manganese salt in an air atmosphere for 2 h˜10 h to form Mn2O3; S02: mixing Mn2O3 with lithium salt and grinding, reacting in a high-pressure reaction kettle at 100° C.˜200° C. for 36 h˜72 h to form a product of LiMnO2; wherein, the molar ratio of Mn2O3 and Li/Mn in the lithium salt is 1:1˜10:1; S03: adding LiMnO2 to a metal coating reagent and ultrasonic mixing for 2 h˜10 h, drying for 6 h˜24 h, and then calcining at 400° C.˜600° C. for 2 h˜10 h to form an oxide-coated Li1.6Mn1.6O4 lithium ion adsorbent; Wherein, the molar ratio of the metal coating reagent to LiMnO2 is 0.01:1˜0.08:1; S04: performing an acid treatment to the oxide-coated Li1.6Mn1.6O4 lithium-ion adsorbent to form an acidified product, washing the acidified product and drying to form the coated lithium-ion sieve. The cell structure of the coated lithium-ion sieve of the present invention is more stabler and can be reused for many cycles, which solves a problem that traditional HMn2O4 lithium-ion sieve is easy to dissolve.

摘要： A stationary phase for high-performance liquid chromatography including monofunctional primary silane functionalized silica provides improved separation performance for the preparative or process scale purification of cannabidiol (CBD) and tetrahydro-cannabinol (THC). Silica bonded with monofunctional primary silane(s) provides more efficient separation of these molecules through higher resolution values, reduced peak broadening and lower separation impedance, thus enabling higher purity product or more efficient purification process.

摘要： A micro-separator for gas chromatography includes a base substrate having a trench defining a micro-column, and a three-dimensional (3D) porous ceramic-polymer composite disposed in the micro-column and having pores that three-dimensionally connected to each other with periodicity. The 3D porous ceramic-polymer composite includes a ceramic nano-structure, which forms an array of three-dimensionally arranged nano-shells, and a reaction-activating layer combined on a surface of the ceramic nano-structure and including a polymeric reaction-activating material. A thickness of the 3D porous ceramic-polymer composite is 10 μm to 20 μm, a column length of the 3D porous ceramic-polymer composite is 30 cm to 70 cm, and a shell thickness of the ceramic nano-structure is 20 nm to 60 nm. The micro-separator may have improved separation performance and durability.
