Biochar loaded with cobalt ferrate activated persulfate to degrade naphthalene

Abstract

Considering the simple preparation of biochar and the excellent activation performance of cobalt ferrate material, a biochar supported cobalt ferrate composite was synthesized by a solvothermal method.

Efficient degradation of COD from coking wastewater by corncob biochar-modified particles using a three-dimensional electrode reactor

“…Tertiary butanol (TBA) is commonly used as a quencher to test the contribution of ˙OH to the degradation of pollutants due to its high sensitivity to ˙OH. 47 During the experiments, 10 mM TBA was added as a quencher, the current density was 25 mA cm −2 , the particle electrode was dosed at 10 g L −1 , and the reaction was sampled and tested when it was carried out for 120 min.…”

Cobalt/Iron Bimetallic Biochar Composites for Lead(II) Adsorption: Mechanism and Remediation Performance

“…Enhanced stability and higher adsorption capacities have frequently been achieved via composite formation or surface modification. The combination of nZVI with porous carbon materials such as carbon nanotubes [10], activated carbon [11], and biochar [12,13], which have unique pore structures, good chemical stability, and high electrical conductivity, can effectively reduce agglomeration and increase pollutant removal efficiency [14]. In particular, bimetallic carbon composites are considered promising for improving the reactivity of nZVI.…”
