Influence of feedstocks and modification methods on biochar’s capacity to activate hydrogen peroxide for tetracycline removal
TLDR
H2O2 could either enhance or decrease the TC removal by biochar, depending on biochar type, H2O1 concentration and solution pH, but the removal efficiency was still quite low under optimum conditions.About:

Activation of grapefruit derived biochar by its peel extracts and its performance for tetracycline removal.
TL;DR: A novel adsorbent derived from grapefruit peel (GP) based biochar (GPBC) was synthesized by combined carbonization of GP and subsequent activation by GP extracts, granting GPBC-20 more abundant surface functional groups, which exerts the adsorbents superior performance for tetracycline adsorption.

Stabilization of nanoscale zero-valent iron (nZVI) with modified biochar for Cr(VI) removal from aqueous solution.
Haoran Dong,Junmin Deng,Yankai Xie,Cong Zhang,Zhao Jiang,Yujun Cheng,Kunjie Hou,Guangming Zeng +7 more
TL;DR: The surface elemental distribution maps of the nZVI@HCl-BC after reaction with Cr(VI) showed that Fe, Cr and O elements were deposited on the surface of Hcl-BC evenly, indicating that the formed Cr(III)/Fe(III) could settle on thesurface of HCl- BC uniformly rather than coated only on the n ZVI surface.

Removal of Pb(II), Cu(II), and Cd(II) from aqueous solutions by biochar derived from KMnO4 treated hickory wood
TL;DR: In this work, a novel approach was developed to prepare an engineered biochar from KMnO4 treated hickory wood through slow pyrolysis (600°C) that had strong sorption ability and the removal of the heavy metals by the biochars was mainly through surface adsorption mechanisms involving both the surface MnOx particles and oxygen-containing groups.
