Summary: Designing non-metallic catalyst as persulfate (PS) activator for effective organic pollutants degradation in water is challenging. Bovine-derived bone chars (BBCs) were prepared with different temperatures, containing ordered mesoporous structures, which showed high phenol uptake and complete degradation in combination with PS. The BBC700/PS system exhibited excellent phenol mineralization rate and strong anti-jamming capacity to various conditions. The tailored non-metallic catalyst has great potential in water purification.

Summary: This study evaluated the chemical form variation of Mn in Phytolacca acinosa Roxb. residue under different pyrolysis temperatures and its contribution to decontamination efficacy of lead (Pb(II)) and tetracycline (TC). The results showed that pyrolysis temperature is a crucial factor in the bioavailability of Mn and other heavy metals in the biochar, with temperatures under 450 degrees C being most suitable for reutilization. The Mn-enriched phytolaccaceae biochar exhibited preferential sorption towards Pb(II) and TC in the single system, while binary adsorption demonstrated a bridging effect between Pb(II) and TC within a limited concentration range for joint decontamination.

Summary: Sulfide-modified magnetic hydrochar (MHC-S4) was synthesized and found to effectively adsorb Cd(II)/Pb(II) over a wide pH range and achieve fast uptake equilibrium. In single system, MHC-S4 showed excellent adsorption properties with maximum monolayer uptake of 62.49 and 149.33 mg/g for Cd(II) and Pb(II), respectively. However, the binding rate and uptake of metal ions in the binary system were inferior, and Pb(II) exhibited significant inhibition to Cd(II) adsorption onto MHC-S4. The results suggested that sulfide-modified magnetic hydrochar is a high-performance adsorbent for heavy metals removal.

Summary: This study investigated the properties of phosphoric acid-modified biochars (PABCs) prepared at different pyrolysis temperatures. PABCs prepared at higher temperatures had a higher proportion of micropores and showed improved adsorption capacity and rate for sulfadiazine (SDZ). The enhancement in adsorption was attributed to the confinement effect of hydrophobic cavities from the microporous structure and the pi-pi electron-donor-acceptor interaction. PABCs exhibited stable adsorption capacities at a wide pH range or high concentrations of coexisting ions.
