Summary: Layered double hydroxides (LDHs) were used as carriers for microbial consortium in sequencing biofilm batch reactor (SBBR) to enhance phosphate removal. [ZnAl]-LDH showed higher adsorption capacity compared to [Mg-Al]-LDH. LDH-SBBRs exhibited improved removal efficiencies of COD, phosphate and TP with a low C/N ratio and promoted the formation of biofilm with increased biodiversity. The synergistic effects between well-structured LDHs and microorganisms led to enhanced phosphate removal performance in LDH-SBBR, with [Zn-Al]-LDH carrier being the most effective.

Summary: This study found that pre-mixing bone char and anionic surfactants could enhance the dehalogenation effect of trichloroethylene (TCE). Higher concentrations of bone char and surfactants led to faster dehalogenation. In the pre-mixture of 1 g/L bone char and 0.16% anionic surfactants with 30 mM [Fe (II)] green rust addition, 20 μM of TCE was eliminated in 2 hours. Ionic and nonionic surfactants inhibited the dehalogenation reaction.

Summary: This study investigated the abiotic debromination of toxic contaminants in anaerobic soil and groundwater using a layered iron(II)-iron(III) hydroxide with biochars as electron mediators. The results showed that biochars were efficient catalysts for the reductive debromination of Tribromoethylene (TrBE), dibromoethylenes (DBEs), and 1,2-dibromoethane (DBA). The debromination reactions exhibited pseudo-first-order kinetics and were faster in deionized water compared to moderately hard groundwater. Post-pyrolysis activation with CO2 further enhanced the catalytic performance of the biochars.

Summary: This study investigates the oxidation of the antibiotic norfloxacin (NOR) using cyanobacterial nitrogen rich biochars (CBs) as catalysts for peroxydisulfate (PDS). The results show that CB950, pyrolyzed at 950 degrees C, is highly effective in degrading NOR, with a faster degradation rate compared to low pyrolysis temperature (PT) CBs. The high pyrolysis temperature CBs also exhibit full reactivity after repeated uses and high defluorination and mineralization rates. The study suggests that high pyrolysis temperature biochars from algal bloom biomass can be used as catalysts for organic contaminant oxidation.

Summary: This study found that under anoxic conditions, iron oxyhydroxides (such as goethite) can facilitate the oxidation of As(III) while reducing structural Fe(III). The formation of an active metastable Fe(III) phase at the defective surface of goethite, through atom exchange, is responsible for the oxidation of As(III). Defects in goethite significantly enhance electron transfer and atom exchange between surface-bound Fe(II) and structural Fe(III), resulting in an increase in As(III) oxidation. Atom exchange-induced regeneration of active goethite sites facilitates As(III) coordination and electron transfer with Fe(III). These findings shed new light on As risk management in soils and subsurface environments by highlighting the synergetic effects of defects in the Fe crystal structure and Fe(II)-induced catalytic processes on anoxic As(III) oxidation.

Si-Fe(II)-III showed higher reductive dehalogenation reactivity towards carbon tetrachloride (CT) compared to Si-Fe(II)-I and Si-Fe(II)-II. The main component of Si-Fe(II)-III was found to be ferrous silicate (FeSiO3), which differed from Si-Fe(II)-I and Si-Fe(II)-II.

Summary: The bioavailability of arsenic in paddy soil-rice systems is affected by ammonium fertilization, but the mechanisms controlling As transformation are not fully understood. This study found that urea and ammonium bicarbonate fertilizers significantly increased As(III) concentration in porewater, bioavailable As in rhizosphere soil, and the relative abundance of arrA and arsM genes. Moreover, the expression of As transporter genes in rice roots was upregulated, leading to increased translocation efficiency of As(III) from roots to brown rice. Therefore, attention should be paid to As-contaminated paddy fields with ammonium fertilization.

Summary: This study prepared cyanobacterial biochars enriched/doped with non-metallic elements by pyrolysis of biomass amended with different N, S, and P containing compounds. It was found that P doping significantly improved the catalytic reactivity of the biochar, with organic phosphorus dopants showing the best performance. Post-acid-washing further enhanced the catalytic activity, especially the acid-washed triphenyl-phosphate doped biochar, which exhibited the highest degradation rate and NOR mineralization. The high reactivity of P-doped biochar was mainly attributed to its large specific surface areas, high adsorption, high C-P-O content, graphitic P, and non-radical degradation pathway.

Summary: Trace element polluted soils are harmful to human and environmental health. Biochar has potential to reduce soil toxicity, but its effectiveness depends on various factors. In this study, we tested fourteen different biochar materials for their ability to bind Cu and reduce toxicity in a specific polluted soil. Results showed that biochar improved plant growth, reduced soil toxicity, and decreased the availability and activity of Cu ions. Certain biochar materials, such as oil seed rape straw, performed better than others, suggesting the importance of feedstock selection for efficient remediation of polluted soils.
