Comment on “removal of hexavalent chromium by biochar supported nZVI composite : batch and fixed-bed column evaluations, mechanisms, and secondary contamination prevention”

This article aims to discuss (1) the incorrect identification of Cr(III) and Cr(VI) binding energies in the Cr 2p XPS (X-ray photoelectron spectroscopy) spectra of the laden adsorbent (the nZVI-BC sample after Cr(VI) adsorption), (2) misconception regarding the Weber–Morris intraparticle diffusion m...
