In the present work, palygorskite (Pal) was initially subjected to an ion-exchange reaction with silver ions (Pal-Ag(+)). Subsequently, Ag-Pal nanocomposites were assembled by a convenient ultraviolet irradiation technique, using carbon dots (CDs) derived from wool fiber as the reducing agent. The obtained nanocomposites were characterized by powder X-ray diffraction (XRD), ultraviolet-visible ...
Ž In this work, a pharmaceutical preformulation study of four Spanish clays two sepiolites, one . palygorskite and one bentonite is presented, comparing the results obtained with those of three mineral products currently used in pharmaceutical technology. The results showed that the mineralogical and chemical purity of these clays is similar and even higher than that of the three commercial pro...
The effect of acid treatment on the adsorptive capacity a Brazilian palygorskite to remove crystal violet (CV) and congo red (CR) dyes was investigated. raw acid-treated by different HCl solutions (2, 4, 6 mol/L). modifications structure were investigated using X-ray diffraction, fluorescence, Fourier-transform infrared spectroscopy, N2 adsorption/desorption, thermogravimetric differential ther...
