The electrochemical reduction of nitrate to ammonia represents a promising approach for simultaneously eliminating from wastewater and converting waste (nitrate) into valuable resource (ammonia). By employing copper foam (CF) as the substrate, two-stage 3D porous irregular nanorod electrode was fabricated through wet chemical oxidation in-situ reconstruction. composition structure prepared were analyzed using SEM, XPS, AES, XRD. nanorods, with size range 50 nm - 500 nm, intersected one...
In this work, Bimetallic Fe/Cu nanoparticles were successfully stabilized by chelating resin, which was specifically employed for the remediation of hexavalent chromium contaminated wastewater. Based on characterization results, it observed that bimetallic uniformly and well distributed surface resin DOW M4195. The results demonstrated supported exhibited an excellent performance Cr(VI) removal efficiency, reaching up to 99.4%. A series factors, including initial pH, concentration Cr(VI),...
Nanoscale zero-valent iron/copper supported on chelating resin (D-Fe/Cu) was prepared for removing nitrate from water. Batch experiments were carried out to investigate the effect of solution chemistry, including initial pH solution, dissolved oxygen (DO), coexisting anions, and humic acid removal nitrate. Results showed that DO had a significant Coexisting Cl−, SO42−, PO43−, HCO3−, inhibited reduction. The efficiency 95.51%, selectivity N2 52.49% at end reaction. results X-ray photoelectron...
Secondary-treated municipal wastewater (MWW) could supply a viable alternative water resource for cooling systems. Inorganic salts in the concentrated pose great challenge to corrosion control chemicals. In this study, inhibition effect of 1-hydroxy ethylidene-1,1-diphosphonic acid (HEDP), trimethylene phosphonic (ATMP) and 2-phosphonobutane-1,2,4-tricarboxylic (PBTCA) on carbon steel secondary-treated MWW was investigated by means potentiodynamic polarization electrochemical impedance...
Activities and selectivities of iron/palladium (Fe/Pd) bimetallic nanoparticles supported on various resin materials (chelating resins DOW 3N, cation-exchange D001, anion-exchange D201) were studied for the reduction nitrate in water. Scanning electron microscopy–energy dispersive spectrometry transmission microscopy results indicated that Fe/Pd well dispersed without aggregation three supports, indicating favorable supports nanoparticles. The surface chemistry support plays an important...
The supported Cu/Pd bimetallic catalyst could prestore hydrogen and no additional reducing agent is required during the nitrate reduction process. High removal efficiency (96%) low NH 4 + selectivity (<2%) were achieved.
The mixture of 1-hydroxyethane-1,1-diphosphonic acid (HEDP), and polyacrylic (PAA) synthesized hydrolyzed polymaleic anhydride (HPMA) was optimized by using simplex lattice Design-Expert software through calcium carbonate precipitation method. optimum mass ratio HEDP, PAA HPMA obtained at 10/10/80, which showed excellent performance on controlling deposition. antiscale efficiency the 84% 95%, respectively, in test scale deposit test. could disturb crystal growth then affect morphology...
Abstract Secondary-treated municipal wastewater (MWW) is the alternative water source in recirculating cooling systems. Municipal treatment plant (WWTP) effluent was collected and four fractions including hydrophobic acidic (HPOA), alkaline (HPOB), weakly (WHPO) hydrophilic (HPI) organics were isolated from by using DAX-8/XAD-4 resin. We used potentiodynamic polarization (PDP) electrochemical impedance spectroscopy (EIS) to investigate corrosion characteristics of N80 carbon steel different...
An innovative Pd-Me (Pd-Cu, Pd-In and Pd-Sn) bimetallic catalyst supported on porous chelating DOWEX M4195 resin (D) was established to reduce the nitrate almost entirely achieved high selectivity expected harmless form of nitrogen. In this study, sodium borohydride (NaBH4) applied in preparing catalysts by liquid-phase reduction as prestoring reductant. Pd-In/D Pd-Sn/D groups performed well N2selectivity (all above 97%). addition, Pd-Sn catalysis yields higher towards N2than Pd-Cu pair...
Nitrate pollution in surface water and ground has drawn wide attention, which brought challenges to human health natural ecology. Electroreduction of nitrate NH3 waste was a way turn into wealth, attracted interest many researchers. Using Nickel foam as substrate, we prepared Pd/In bimetallic electrode (NF-Pd/In) according two-step electrodeposition method. There are irregularly shaped particles the size range 10 nm -100 accumulated on NF-Pd/In electrode, could supply high specific area more...
Nitrate pollution in ground water and surface has been becoming a worldwide problem that poses great challenge to steady ecosystem human health. Electrochemical reduction of nitrate is promising way remove from because advantages. We prepared Pd/Sn modified nickel foam (NF) electrode according two-step electrodeposition method. The NF-Pd/Sn showed micromorphology like “Karst Fengcong” with peaks, saddles nadirs intertwined each other. Pd 0 Sn were detected on the mass ratio was 4.3/1....
