Nitrite reduction by copper complexes.
A series of copper complexes have been synthesised as potential agents for the catalytic reduction of nitrite anions. The ligands and corresponding copper complexes have been characterised by using a range of techniques including X-ray crystallography, NMR, microanalysis, mass spectrometry, infra-red spectroscopy, electrochemical studies and density functional theory calculations. For complexes...
متن کاملKinetic Characterization of Nitrite Uptake and Reduction by Chlamydomonas reinhardtii.
Kinetics of nitrite uptake and reduction by Chlamydomonas reinhardtii cells growing phototrophically has been studied by means of progress curves and the Michaelis-Menten integrated equation. Both uptake and reduction processes exhibited hyperbolic saturation kinetics, the nitrite uptake system lacking a diffusion component. Nitrite uptake and reduction showed significant differences in K(s) fo...
متن کاملReduction of nitrate and nitrite by subcellular preparations of Anabaena cylindrica. I. Reduction of nitrite to ammonia.
Reduction of nitrite by cell-free preparations of Anabaena cylindrica in the dark has been investigated. Nitrite-reducing activity was recovered in a supernatant fraction. The nitrite reductase system was partially purified by column chromatography on Sephadex G-75. NADPH could serve as an H-donor. NADH was completely inactive. The reduction required ferredoxin which mediated the transfer of el...
متن کاملNew Polymer Catalytic Membranes for Nitrite Reduction: Experimental Assessment
In this work we report the experimental assessment of the performance of a new catalytic hollow fiber reactor with supported Pd catalyst for nitrite removal from polluted waters. The reactor configuration facilitates working at low flowrate and hydrogen concentrations in order to improve the selectivity of the reduction reaction towards nitrogen, thus, inhibiting the formation of ammonia. Pd ca...
متن کاملNitrate reduction to nitrite, a possible source of nitrite for growth of nitrite-oxidizing bacteria.
Growth yields and other parameters characterizing the kinetics of growth of nitrite-oxidizing bacteria are presented. These parameters were measured during laboratory enrichments of soil samples with added nitrite. They were then used to reanalyze data for nitrite oxidizer growth in a previously reported field study (M. G. Volz, L. W. Belser, M. S. Ardakani, and A. D. McLaren, J. Environ. Qual....
