通过实验研究，可得以下结论： 1. β-环糊精（β-CD）作用下碳酸镧晶体的合成。制备出花状碳酸镧，颗粒大小约为10μm；制备出两端不同粗细的碳酸镧纳米管，管长约为2μm，管粗约为300~400nm。 2. 聚乙烯醇(PVA)作用下碳酸镧晶体的合成。制备出六棱片层碳酸镧，颗粒大小约为8μm；制备出碳酸镧纳米棒，棒长约为2μm，管粗约为300~400nm。 3. 以棉花为模板碳酸镧晶体的合成。制备出大小约为10μm的树状碳酸镧颗粒。 4. 通过钼锑抗法测定碳酸镧的磷结合效果。与磷结合能力最强的样品为聚乙烯醇作用下合成的碳酸镧纳米棒，此样品与磷酸盐溶液反应，达到反应终点所需时间最短，且终点溶液中磷含量最少。 |

Through experimental research, the following conclusions can be drawn: 1. Synthesis of Lanthanum carbonate Crystals under the action of Β-cyclodextrin (β-CD) . Lanthanum carbonate prepared flower-like, particle size is about 10μm; prepared with different thickness of lanthanum carbonate at both ends of nanotubes, tube length is 2μm, Coarse about 300 ~ 400nm. 2. Polyvinyl alcohol (PVA) under the action of lanthanum carbonate Crystals. Preparation of a six-rowed lanthanum carbonate layers, particle size is about 8μm; prepared lanthanum carbonate nanorods, rod length is 2μm, Coarse about 300 ~ 400nm. 3. To cotton as the template synthesis of lanthanum carbonate crystals. Size of approximately 10μm was prepared tree lanthanum carbonate particles. 4. Through the determination of molybdenum antimony anti-P combined effects of lanthanum carbonate. The strongest binding with the phosphate sample as the synthesis of polyvinyl alcohol under the action of lanthanum carbonate nanorods, the reaction of the sample and the phosphate solution to achieve the shortest time the reaction end, and the phosphorus content of at least the end solution. |
