Synthesis and use of reactive metal particles have shown significant environmental implications for the remediation groundwater sediment contaminated with chlorinated compounds. Herein, we developed an effective strategy, employing a series innovative granular activated carbon (GAC) composites incorporated iron/palladium (Fe/Pd) bimetallic nanoparticles. The physical adsorption polychlorinated biphenyls (PCBs) to GAC their electrochemical dechlorination by Fe/Pd bimetal on could be...
There are many concerns and challenges in current remediation strategies for sediments contaminated with polychlorinated biphenyls (PCBs). Our efforts have been geared toward the development of granular activated carbon (GAC) impregnated reactive iron/palladium (Fe/Pd) bimetallic nanoparticles (reactive (RAC)). In this study, we elucidate mechanistic aspects hybrid RAC system dechlorinating 2-chlorobiphenyl (2-ClBP) aqueous phase. The following reactions occurred parallel or consecutively:...
A commercially available, 3D printer nanocomposite filament of carbon nanotubes (CNTs) and acrylonitrile–butadiene–styrene (ABS) was analyzed with respect to its VOC emissions during simulated fused deposition modeling (FDM) compared a regular ABS filament. were quantified characterized under variety conditions simulate the thermal degradation that takes place FDM. Increasing residence time temperature resulted in significant increases emissions, oxygen content reaction gas influenced...
Polychlorinated biphenyls (PCBs) are toxic pollutants notorious for their aquatic and sedimentary prevalence recalcitrant nature. Bimetallic systems like Pd/Fe have been widely studied degrading them. Mg, with oxidation potential higher than Fe, has reported to dechlorinate PCBs in conjunction K2PdCl6-systems that distinct from Pd/Mg bimetals. This study primarily aims evaluate bimetallic dechlorinating 2-chlorobiphenyl (2-CIBP), a model PCB. Candidacy of Mg is based on its unique corrosion...
Flue gas from coal combustion contains significant amounts of volatile toxic trace elements such as arsenic (As), selenium (Se), and mercury (Hg). The capture these in the flue desulphurization (FGD) scrubber unit has resulted generation a metal-laden residue. With increasing reuse FGD residues beneficial applications, it is important to determine metal speciation mobilityto understand environmental impact its reuse. In this paper, we report solid phase As, Se, Hg using X-ray absorption...
The transport properties of titanium dioxide (anatase polymorph) nanoparticles encapsulated by carboxymethyl cellulose (CMC) were evaluated as a function changes in the solute chemical clean quartz, amorphous aluminum, and iron hydroxide-coated sands. While pristine anatase TiO2 (ANTNPs) completely immobile, presence CMC significantly enhanced their mobility. magnitude surface charge exhibited CMC-coated (CMC-ANTNPs) exceeded that uncoated ANTNPs, thereby leading to negative over pH range...
