Curcumin is a natural polyphenol that is used in various traditional ***,its inherent properties,such as its rapid degradation and metabolism,low bioavailability,and short half-life,are serious problems that must be *** this end,a drug carrier incorporating natural magnetic cores in a zeolite framework was developed and applied to the loading of curcumin in ethanol *** this system,curcumin is encapsulated in a zeolite Na(ZNA)magnetic core–shell structure(Fe@Si/ZNA),which can be easily synthesized using an in situ *** of Fe_(3)O_(4) nanoparticles was carried out from natural materials using a co-precipitation *** of the prepared magnetic core–shell structures and composites was carried out using vibrating-sample magnetometery,Fourier transform infrared spectroscopy,transmission electron microscopy,and x-ray *** cumulative loading of curcumin in the ZNA composite with 9%nanoparticles was found to reach 90.70%with a relatively long half-life of 32.49 *** tests of curcumin loading in the composite showed that adding magnetic particles to the zeolite framework also increased the stability of the composite *** kinetics and isotherm studies also found that the system follows the pseudo-second-order and Langmuir isotherm models.
