摘要: Abstract The topotactic transformation from magnetite to maghemite sub-microparticles was demonstrated by a variety of techniques that include X-ray diffraction, Raman spectroscopy, electron microscopy, Mossbauer magnetic measurements, and vis-NIR diffuse reflectance. physical, chemical, morphological properties the particles were correlated with their adsorptive in water respect arsenic (V). iron oxide are increased changing crystal phases involved, specifically, maghemite. Maghemite capable efficiently decreasing content 100 ppb below World Health Organization (WHO) guideline 10 ppb.
