TL;DR: Investigation of chitosan-PMDA modified biochar as an adsorbent for the removal of heavy metal ions from single metal and mixed-metal solutions found it had selective adsorption capacity for copper due to the N-containing functional groups.

TL;DR: In this paper, a new environmentally friendly and low-cost adsorbent to remove As(V) from industry waste water was synthesized by the mixture of 723 K pyrolyzed chestnut shell and magnetic gelatin.

TL;DR: The experimental results suggest that the adsorption efficiency of DOX is dominated by the strong complexation, electrostatic interactions between DOX molecules and the Cu-BC samples, which hold the significant potential for enhancing the effectiveness to remove DOX from water.

TL;DR: In this article, Nitrilotriacetic acid-functionalized magnetic graphene oxide (NDMGO) was developed for the removal of ciprofloxacin (CIP) with and without the presence of Cu(II).

TL;DR: The regeneration experiment demonstrated that this nanomaterial possessed an excellent regeneration performance and the NDMGO was a high-efficiency and reusable adsorbent for TC pollution control.

TL;DR: The source and production of biochar is summarized, its research status in the removal of organic pollutants is pointed out, the relevant adsorption parameters are introduced, its regeneration methods are summarizes, its application of engineering is studied, and the development prospects are described.

TL;DR: Modification of biochar derived from sawdust shows great potential for simultaneous removal of Cu(II) and tetracycline from co-contaminated water.

TL;DR: The concentration of heavy metals in several sites, assessed in water, soil and sediment samples, affected by different pollution sources are reviewed, showing how human activities impact natural media and how the pollution spreads.

TL;DR: This review evaluates various methods to increase the sorption efficiency of biochar including activation with steam, acids and bases and the production ofBiochar-based composites with metal oxides, carbonaceous materials, clays, organic compounds, and biofilms.

TL;DR: The most common adsorption mechanism can be considered as electron donor-acceptor interactions of electron withdrawing moieties with surface arene rings where the dominant species are zwitterionic or cationic.
