摘要
通过浸渍热解法制备Ti/BiFeO3催化剂电极,以H2O2为氧化剂、玉米淀粉为原料制备了氧化玉米淀粉,并通过压片法制备的淀粉负载氨咖黄敏药片研究其对氨咖黄敏在水中的缓释性能。扫描电子显微镜(SEM)、红外光谱(FT-IR)、X射线衍射(XRD)以及黏度等测试表明,氧化淀粉颗粒表面粗糙且产生明显裂缝,结晶度、粘度和糊化温度明显下降。与NS相比,制备的OS在270 min之内对氨咖黄敏具有更加均匀的释放速率。在pH=9时AHC的缓释效果最好,而温度影响不明显。
The Ti/BiFeO3 catalyst electrode was prepared by immersion pyrolysis method.Oxidized starch was prepared with H2O2 as the oxidant and corn starch as the raw material,and the starch-loaded Anka Huangmin tablets were prepared by the tableting method its slow-release performance of Anka Huangmin in water.Scanning electron microscope(SEM),infrared spectroscopy(FT-IR),X-ray diffraction(XRD)and viscosity tests showed that the surface of oxidized starch particles was rough and had obvious cracks,and the crystallinity,viscosity,and gelatinization temperature decreased significantly.Compared with NS,the prepared OS has a more uniform release rate of Anka Huangmin within 270 min.At pH=9,the sustained release effect of AHC is the best,but the temperature effect is not obvious.
