Published in 2017 at "Journal of environmental chemical engineering"

DOI: 10.1016/j.jece.2017.07.027

Abstract: Abstract The biogenic hydroxyapatite (BHAP), obtained by proper treatment of bovine bones, was functionalized with 5-aminosalicylic acid (5-ASA). The coordination of 5-ASA to the surface of BHAP leads to the charge transfer (CT) complex formation… read more here.

Published in 2020 at "Journal of hazardous materials"

DOI: 10.1016/j.jhazmat.2020.124140

Abstract: Amino-modified attapulgite (M-ATP) was prepared to remove Pb2+ and Cu2+ from the aqueous solution. Fourier transform infrared spectroscopy (FT-IR) spectrums and X-ray powder diffraction (XRD) patterns revealed that a new Si-O-Si bond formed after modification.… read more here.
