The pollution of hexavalent chromium (Cr (VI)) in soil is a serious environmental issue.
Herein, nanoscale zero-valent iron (NZVI) supported on rice husk-derived biochar (RBC) …

The stability of biochar is a major determinant of its potential for carbon sequestration. In
previous studies, the biochar stability was evaluated by analyzing the oxidation resistance …

Salinization is a global soil degradation issue threatening agricultural productivity and
environmental sustainability. Native biochar is a promising soil amendment, but its high …

Biochar (BC) has been evidenced as an effective material to enhance the soil capacity of
carbon (C) sequestration. However, the influence of mineral ion-modified BC on soil organic …

A new heterogeneous Fenton catalyst, Fe-impregnated biochar catalyst (Fe-BC) was
synthesized and evaluated in detail for its catalytic activity with sulfate radical under various …

Application of wood ash on forest and agricultural soils can provide nutrients and increase
soil pH, however, it changes the soil chemistry rapidly and temporarily, often resulting in …

Metal-blending of biomass prior to pyrolysis is investigated in this work as a tool to modify
biochar physico-chemical properties and its behavior as adsorbent. Six different compounds …

Ferrous sulfate, known as copperas, is generated from the titanium dioxide manufacturing
industries. This by-product has been used in cement processing, agriculture, animal feed …

Background Fostering plant growth and improving agricultural yields by adding “macro”-
sized biochar to soil has been extensively explored. However, the impact and mechanism of …

Sludge-based biochar was first modified for the adsorption of phosphorus from aqueous
solution. This study is to modify sludge-based biochar (SBC) via peroxidation with nitric acid …
