Abstract
Objective To synthesize high medicinal value lanthanum carbonate,and characterize the synthetic sim-ples.Methods Lanthanum carbonate was synthesized by lanthanum chloride and sodium bicarbonate.It can be synthesized by changing synthesis conditions,which include adjusting pH value and adding different additives.Furthermore,the synthet-ic samples were characterized by several techniques including X -ray diffraction (XRD),Fourier transform infrared spec-trometer (FTIR),scanning electron microscopy (SEM),and Thermo gravimetric analyzer (TGA).Results The results showed that layer -crystal was synthesized by adding ethanol in the synthetic systems,and the crytal size was 20 ~50 μm with a layer up to 0.6 ~0.8 μm thick.Conlusion The higher specific surface area of lanthanum carbonate was more fa-vorable to the combination of phosphate,and can reduce the absorption of phosphorus in the gastrointestinal tract.关键词
