DOI: 10.1016/j.aca.2020.05.023

Abstract: A series of different facile modification layers (MLs) was designed to gradually increase the electrochemical sensing performance of glassy carbon electrode (GCE) for simultaneously detecting Pb2+ and Cu2+. ML designs were mainly a different combination… read more here.

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.

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.

DOI: 10.1346/ccmn.2017.064058

Abstract: The adsorption properties of clay minerals (e.g. montmorillonite and palygorskite) have been improved through chemical treatment methods. However, the addition of extra chemicals is often not friendly to the environment and powdered clay-mineral adsorbents are… read more here.
