KOH-activated high surface area Douglas Fir biochar for adsorbing aqueous Cr(VI), Pb(II) and Cd(II)

Amali Herath et al.

Summary: Through KOH activation, high surface area Douglas fir biochar obtained from commercial syn-gas production shows remarkable enhancement in heavy metal adsorption capacity for Cr(VI), Pb(II) and Cd(II). The adsorption process follows pseudo-second order kinetics and the Langmuir adsorption model for all three metals. The desorption study reveals that Pb(II) adsorption onto KOH-activated biochar surface is reversible, while portions of Cd(II) and Cr(VI) adsorbed strongly onto the biochar cannot be desorbed by typical solutions.

Adsorptive removal and recovery of organic pollutants from wastewater using waste paper-derived carbon-based aerogel

Thi Huong Pham et al.

Summary: This study explored the use of carbon-based aerogels derived from waste paper as efficient adsorbents for removing organic pollutants from wastewater, achieving significant removal efficiency with low-concentration pollutants through electrostatic attraction, pore-filling, hydrogen bonding, and pi-pi interactions. This work provides an effective approach to produce adsorbents for the removal and recovery of chemicals from wastewater.

Removal of Cd from aqueous solution by chitosan coated MgO-biochar and its in-situ remediation of Cd-contaminated soil

Jiangxin Xiang et al.

Summary: The magnesium oxide biochar-chitosan composite modified with MgCl2 and chitosan demonstrated high Cd adsorption capacity and effective Cd stabilization in soil, reducing both bioavailable and acid-extractable Cd content while increasing residual Cd content. The synergistic effect of surface complexation and precipitation mechanisms played a major role in Cd removal, highlighting the potential of MgO-BCR-W as an effective and eco-friendly adsorbent for Cd remediation in water and soil environments.

High-efficiency removal capacities and quantitative adsorption mechanisms of Cd2+ by thermally modified biochars derived from different feedstocks

Heng Wang et al.

Summary: The adsorption characteristics of Cd2+ on three biochars modified by pyrolysis and calcination were investigated, showing TCMB had the highest adsorption capacity and reusability. Precipitation and cation-exchange were found to dominate the chemisorption process, while complexation played a minor role.
