| Abstract |
Halloysite nanotubes (HNTs), tubular clay mineral, are naturally occurring clay mineral. Pristine halloysite nanotubes (HNTs) were pretreated to produce acid treated halloysite nanotubes which have enlarge pore and surface area. Amine-functionalized HNTs (A-HNTs) were prepared after surface modification of acid-treated HNTs by 3-aminopropyltriethoxysilane, which can be used as an adsorbent for 2-(2,4,5,7-tetrabromo-6-oxido-3-oxo-3H-xanthen-9-yl)benzoate) [eosin Y] that is most commonly used as an acidic red stain. The dye is also not specifically listed as a toxic substance by different health agencies. Because of its stability, non-toxicity and complex aromatic structure, eosin Y is used in the fields of leather, printing, dyeing, printing ink, fluorescent pigment, photo-photocatalyst, and so on. We compared the corresponding adsorption capacity of acid treated HNTs and A-HNTs. Characteristics of prepared A-HNTs were examined by mean of the Brunauer−Emmett−Teller (BET), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and ultraviolet–visible spectroscopy. |
