Development of a Gold Amalgam Voltammetric Microelectrode for the Determination of Dissolved Fe, Mn, O2, and S(-II) in Porewaters of Marine and Freshwater Sediments.
Paul J. Brendel,George W. Luther +1 more
TL;DR: A solid-state voltammetric gold amalgam microelectrode has been developed for the measurement of dissolved O 2, S(-II), Fe, and Mn in the porewaters of marine sediments as mentioned in this paper.
Journal ArticleDOI
Interactions of manganese with the nitrogen cycle: Alternative pathways to dinitrogen
TL;DR: In this article, the authors provided field and laboratory evidence that N2 can also be produced by the oxidation of NH3 and organic-N with MnO2 in air and showed that these two reactions are more favorable as a couple than the oxidization of organic matter by O2 alone.
Journal ArticleDOI
Use of voltammetric solid-state (micro)electrodes for studying biogeochemical processes: Laboratory measurements to real time measurements with an in situ electrochemical analyzer (ISEA)
George W. Luther,Brian T. Glazer,Shufen Ma,Robert E. Trouwborst,Tommy S. Moore,Edouard Metzger,Chareonkwan Kraiya,Tim J. Waite,Gregory K. Druschel,Bjørn Sundby,Martial Taillefert,Donald B. Nuzzio,Timothy M. Shank,Brent L. Lewis,Paul J. Brendel +14 more
TL;DR: In this article, solid-state voltammetric (micro) analyzers have been used in a variety of environments to study biogeochemical processes, such as sediment, microbial mats, cultures and the water column including hydrothermal vents.
Journal ArticleDOI
Simultaneous measurement of O2, Mn, Fe, I−, and S(—II) in marine pore waters with a solid-state voltammetric microelectrode
George W. Luther,Paul J. Brendel,Brent L. Lewis,Bjørn Sundby,Lucie Lefrançois,Norman Silverberg,Donald B. Nuzzio +6 more
TL;DR: A solidstate Au/Hg voltammetric microelectrode was used to measure, simultaneously and with millimeter spatial resolution, the vertical distributions of O 2, Mn 2+, Fe 2-, HS, and I - in the pore water of sediments from the Canadian continental shelf and slope as mentioned in this paper.
Journal ArticleDOI
Sulfur speciation monitored in situ with solid state gold amalgam voltammetric microelectrodes: polysulfides as a special case in sediments, microbial mats and hydrothermal vent waters.
George W. Luther,Brian T. Glazer,Laura Hohmann,Jeannette I. Popp,Martial Taillefert,Timothy F. Rozan,Paul J. Brendel,Stephen M. Theberge,Donald B. Nuzzio +8 more
TL;DR: The voltammetric data show that polysulfides are the first detectable intermediate during sulfide oxidation which is consistent with previous laboratory studies.
