Preparation, Characterization, and Ninhydrin Removal by Al۲O۳ and V۲O۵ Nanoparticles

Two nanoparticles, aluminum dioxide (Al۲O۳) and vanadium pentoxide (V۲O۵) were prepared by hydrothermal autoclave and reflex methods, respectively. Every nanoparticle was heated at two temperatures (۹۰ °C and ۴۰۰°C). The structures and surface morphology of these nanoparticles were characterized by FT-IR and UV/Visible measurements, X-ray diffraction (XRD), atomic force microscope (AFM), and scanning electron microscopy (SEM). The ninhydrin removal was measured for these nanoparticles. The results showed vanadium pentoxide has a higher ninhydrin removal activity in both cases (۹۰ °C and ۴۰۰ °C) than the aluminum oxide and the nanoparticles heated at ۴۰۰ °C have more ninhydrin removal activity than the nanoparticles heated at ۹۰ °
