Through experimental research, the following conclusions can be drawn:
1. Synthesis of carbonate Lanthanum Crystals under the action of Β-cyclodextrin (β-CD) . Flower-like carbonate Lanthanum has been prepared with the particle size of about 10μm; Besides, carbonate lanthanum nanotubes with different diameters at both ends have also been prepared with the tube length of about 2μm and diameters of about 300 ~ 400nm.
2. Synthesis of carbonate Lanthanum Crystals under the action of Polyvinyl alcohol (PVA). The six-rowed layered carbonate lanthanum crystals have been prepared with the particle size of about 8μm; Carbonate lanthanum nanorods have also prepared with the rod length of about 2μm and diameter of about 300 ~ 400nm.
3. Synthesis carbonate of lanthanum crystals based on the cotton template. Tree-like carbonate lanthanum particles with the size of about 10μm have been prepared.
4. The ability for carbonate lanthanum to combine with P was measured by anti-molybdenum (antimony) method. It found that the strongest binding with the phosphate sample was the carbonate lanthanum nanotubes synthesized under the action of polyvinyl alcohol. The reaction of the sample and the phosphate solution took the shortest time to the end, and the least phosphorus content remained in the end solution. |
