Journal ArticleDOI
Key Role of Persistent Free Radicals in Hydrogen Peroxide Activation by Biochar: Implications to Organic Contaminant Degradation
TL;DR: It was found that H2O2 can be effectively activated by biochar, which produces hydroxyl radical ((•)OH) to degrade 2-CB and the activation mechanism was elucidated by electron paramagnetic resonance (EPR) and salicylic acid (SA) trapping techniques.
Journal ArticleDOI
Sorption of Zn(II), Pb(II), and Co(II) using natural sorbents: equilibrium and kinetic studies.
TL;DR: The overall sorption capacity decreased after acid treatment, as this decreased the extent of precipitation on calcite and dolomite, and the effect of Zn(II) ions concentration on sorption kinetics was investigated.
