“…XPS signals for Ni(OH)2 are typically 855 eV -858 eV for the Ni 2p3/2 and 531 eV for the O 1s binding energies, which are in agreement with the results found here (vide supra) (Dube et al 1995, Grosvenor et al 2006, Mcintyre and Cook 1975. The cause of the O 1s shift to near 533 eV is uncertain, but may be due to interactions between the Ni(OH)2 nanoparticles and oxygen functional groups on the CFE that may form during the oxidative electrodeposition process under basic conditions.…”

(academic)Recovering valuable resources from wastewater will transform wastewater management from a treatment focused to sustainability focused strategy, and creates the need for new technology development. An innovative treatment concept -osmotic bioelectrochemical system (OsBES), which is based on cooperation between bioelectrochemical systems (BES) and forward osmosis (FO), has been introduced and studied in the past few years. An OsBES can accomplish simultaneous treatment of wastewater and recovery of resources such as nutrient, energy, and water (NEW). The cooperation can be accomplished in either an integrated (osmotic microbial fuel cells, OsMFC) or coupled (microbial electrolysis cell-forward osmosis system, MEC-FO) configuration.In OsMFC, higher current generation than regular microbial fuel cell (MFC) was observed, resulting from the lower resistance of FO membrane. The electricity generation in OsMFC could greatly inhibit the reverse salt flux. Besides, ammonium removal was successfully demonstrated in OsMFC, making OsMFCs a promising technology for "NEW recovery" (NEW: nutrient, energy and water). For the coupled OsBES, an MEC-FO system was developed. The MEC produced an ammonium bicarbonate draw solute via recovering ammonia from synthetic organic solution, which was then applied in the FO for extracting water from the MEC anode effluent. The system has been advanced with treating landfill leachate. A mathematical model developed for ammonia removal/recovery in BES quantitatively confirmed that the NH4 + ions serve as effective proton shuttles across cation exchange membrane (CEM). Resource Recovery by Osmotic Bioelectrochemical Systems towards Sustainable Wastewater TreatmentMohan Qin Abstract (general audience)Nowadays, wastewater is no longer considered as waste. Instead, it is a pool for different kinds of resources, such as nutrient, energy, and water (NEW). Various technologies were developed to achieve NEW recovery from wastewater. A novel concept, osmotic bioelectrochemical system (OsBES) has been introduced and studied in the past few years. OsBES is based on two technologies: bioelectrochemical systems (BES) and forward osmosis (FO); and the corporation between these two technologies could accomplish simultaneous wastewater treatment and resource recovery. We investigated two kinds of OsBES: one is osmotic microbial fuel cells (OsMFC), and the other is microbial electrolysis cell-forward osmosis system (MEC-FO). For OsMFC, a mathematical model was built to understand the internal resistance, which will affect the current generation according to Om's law (I=U/R). The salt transport across the cation exchange membrane (CEM) is related to the current generation. The ion transport, especially ammonium/ammonia transport, across CEM membrane in BES was modelled, which will help the BES design and operation for ammonia recovery systems. The system performance for wastewater treatment and resource recovery in MEC-FO was fully investigated with both synthetic wastewater and landfill leach...

“…There are only two articles related to the deposition of metal alloys with the use of metal complexes containing heteronuclear metals. 17,18 In these studies Cu-Ni trans-metallation complexes were prepared by the use N,N¢-diethyl nicotine amide ligand to deposit Ni-Cu alloys with different stoichiometry on metal surfaces. The alloys thus prepared were characterized with X-ray diffraction (XRD), Auger and X-ray photoelectron spectroscopy (XPS) techniques.…”

“…1 these complexes contain two different metal ions in the same molecule. The metal alloys were electrodeposited from trinuclear complexes similar to the study of Dube et al 17 The related electrodeposition potentials were determined from cyclic voltammetry (CV) curves taken at different scan rates and potential ranges. The metal alloys were then electrodeposited on St-42 discs mounted on rotating disc electrode assembly at different rotation rates, the disc was then dismantled from the electrode system and the coverage was analyzed first with XRD then X-ray fluorescence (XRF), atomic absorption spectrometer (AAS) and ion chromatography (IC) techniques.…”

M 1 II -M 2 II -M 1 II type linear complexes (where M 1 = Ni 2+ , Cu 2+ and M 2 = Cu 2+ , Zn 2+ , Co 2+and Cd 2+ were prepared and dissolved in dimethyl sulfoxide. They were then electrodeposited on mild steel surfaces by the use of rotating disc electrodes. The deposition potentials were determined from cyclic voltammetric i-E scans. The metal films deposited on mild steel surfaces were characterized with atomic absorption spectrometer (AAS), X-ray fluorescence (XRF) and ion chromatography (IC) methods. Although the stoichiometric quantity of M 2 metal cation was half of the M 1 metal cation in the complex, the amount of M 2 metal deposited upon the surface was markedly greater. The amount of M 2 ion deposited on the surface was found to increase with the hardness of the ion. The X-ray diffraction (XRD) patterns showed that the excessively deposited metal on the surface was in metallic form as well as alloy. The size of the deposited film particles was investigated by the use of atomic force microscope (AFM) technique and the particles were observed to be bigger than nanoparticle size.

The nickel-copper alloy (70:30) prepared by metallurgical route is currently employed in marine environments because of its good resistance to corrosion. This alloy forms a thin protective surface layer when exposed to marine atmosphere and thus provides its corrosion resistance. Electrodeposition of nickel-copper alloy from sulphamate acetate-based electrolyte is a new and novel approach and was experimented. The detailed study was performed on the effect of electrolyte composition, current density and pH on the preparation of alloy deposit; the prepared alloy deposit particle size is of 78 nm, and the surface morphology of the alloy deposit was characterized with X-ray diffraction, scanning electron microscopy, EDAX, and atomic force microscope. Nickel-copper alloy deposited from the sulphamate acetate-based electrolyte operated at a temperature of 30°C, with a pH of 6.6 and at 3 A/dm 2 , produces nickelcopper (70:30) alloy deposit. The corrosion behaviour of this alloy deposit was studied by potentiodynamic polarization method; the corrosion current of nickel is 8.67 lA cm -2 and the nickel-copper alloy is 2.65 lA cm -2 .
