This book was released on 1988 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: The electrochemical reduction of nitrate ions in alkaline solution has been studied using various cathode materials and is the basis for a patent describing the conversion of nitrate into hydroxide ion in carbonate solutions. Recently, Taniguchi et al. have reported that certain well studied transition metal cyclic amine complexes, namely Co(III)-cyclam and Ni(II)-cyclam where cyclam is 1,4,8,11-tetraazacyclotetradecane, efficiently electrocatalyze the reduction of nitrate and nitrite to hydroxylamine at mercury electrodes. Here the authors report that the metal cyclam catalyst can be incorporated into a Nafion film electrode, and that the reduction of nitrate and nitrite proceeds efficiently at these electrodes in concentrated NaOH solution. Nafion is a perfluoroalkanesulfonated cation exchange material that has been widely used to immobilize redox couples at electrode surfaces, including electrocatalysis species.

This book was released on 2020-02-13 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon nanomaterials possess special physical and chemical properties. As adsorbents, they are widely used for the purification of water and other liquids, recovery of valuable substances from liquid and gaseous media, and oil refining and also in petrochemical, wine, oil and fat, and other industries. They can be used in medicine, both for the creation of hemosorption systems that are capable of performing specific purification of blood and other physiological fluids, including removal of various exo- and endotoxicants, and for the construction of highly effective adsorbed probiotics. The creation of nanostructured carbon-containing materials is one of many rapidly developing research fields and also the theme of this book. The book focuses on the recent developments in the synthesis of nanostructured carbon multifunctional sorbents and covers topics such as fusicoccin compounds as anticancer agents, entero- and vulnerosorption, and blood purification. It will be useful for scientists, chemical industry specialists, professors, and master’s and PhD students of chemical, physical, and biological sciences.

This book was released on 2020 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this study is to introduce a new undivided cell capable of simultaneous removal of nitrate and ammonia from wastewater streams using CuNi-PtIr supported on carbon (CuNi-PtIr/C) catalysts. The Environmental Protection Agency (EPA) considers ammonia (NH3) and nitrate (NO3-) as a large-scale threat to environmental quality and human health, causing impaired air quality, surface water eutrophication, and other serious health problems. This project focuses on introducing new classes of CuNi-PtIr/C catalysts for efficiently simultaneous removal of ammonia and nitrate through a pulse electrolysis technique in an undivided flow cell system. A systematic study has been conducted to examine different compositions of PtIr/C and CuNi/C catalysts using electrochemical techniques, and it was found that 40% Cu9Ni/C and 60% Pt9Ir/C are the most efficient catalysts for the nitrate reduction and ammonia oxidation, respectively. The introduced process enables the reduction of nitrate and the direct oxidation of ammonia to nitrogen with the co-generation of hydrogen in alkaline media. The co-generated hydrogen can be used for further recovery of the energy. Using the introduced technique, in some cases, after a few hours of electrolysis, no nitrate was left at the end. The ammonia concentration decreased from 2000 ppm to below 100 ppm, with an average current density of about 30-50 mA/cm2 (depending on electrolysis condition and electrode properties). Using this undivided flow cell, we were successful in simultaneously removing nitrate and ammonia. The proposed undivided flow cell uses 65-90% less energy than the existing processes. Because of this advantage, this technique could be implemented for the nitrate/ammonia decontamination of multiple lakes, rivers, and ponds.

This book was released on 1995 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the experimental and modeling work performed to evaluate porous cathodes for the electrochemical reduction of nitrites in liquid wastes. The experiments were done using the MP{dagger} cell with two different porous cathodes: nickel foam and TySAR{trademark}SB{double_dagger}. The experimental results are compared with each other and to those obtained with a planar nickel cathode. The results show that the ammonia production reaction is the dominant cathodic reaction ((approximately)80% efficiency) for all three electrodes. The temperature range used in this study was 29-37 {circ}C while the catholyte feed was either 0.6M NaNO2 or 1.9M NaNO3, both supported by a 1.33 M NaOH solution. All experiments used a constant current density of 0.25 A/cm2. The experimental results suggest that the porous nickel electrode at lower temperatures ((approximately)31{circ}C) is the most efficient of the three electrodes for the reduction of nitrates and nitrites. The porous nickel electrode exhibited the highest conversion of nitrates and nitrites, and the lowest overpotential for a given current density. The partial current fractions at known catholyte concentrations were used to extract the exchange-current densities for the five cathodic reactions. Using these kinetic parameters, dynamic simulations of the four hour experiments were performed. Agreement was found between the model and experimental results for changes in the moles of the nitrate and nitrite and the cell overpotential with time. Future work will determine the effects of temperature and current densities on the exchange-current densities and reaction product distributions. The performance of other porous cathode materials (TySAR{trademark}EP{section}, TySAR{trademark}IM) will also be evaluated.
