Intercalation of Phenylalanine, Isocoumarin and Ochratoxin A (OTA) into LDH’s

Abstract

Phenylalanine, isocoumarin and Ochratoxin A (OTA) have been intercalated within the interlayer space of layered double hydroxides. Synthesis of these nanocompounds was achieved via co-precipitation. Their physicochemical properties were studied by element chemical analysis, powder X-ray diffraction, infrared spectroscopy and thermal analyses. The presence of OTA in the interlayer is demonstrated by the study of LC-FD Analysis. On the other hand, these studies allow to check how some of the toxin is on the surface of the nanocomposite.

“…The weak absorptions at 770 cm −1 was observed in Cop-RC-β-phenylalanine, due to the mono-substituted benzene. 62 Transmission electron microscopy (TEM) was used to determine the morphology, particle size and size distribution. As shown in Fig.…”
