“…Geothermal brines that accompany oil and gas extraction are commonly contaminated with sulfide ions, sometimes at concentrations up to 60 mM. Hydrogen sulfide, which has p K a values of 7.04 and 11.96, is volatile at a pH ∼ 8, typical of these brines, causing diverse problems of odor, toxicity, and metal corrosion. Electrochemical oxidation is of interest as a possible remediation technology for sour brines because chemical treatment methods , involve costly chemicals and sludge disposal.…”

“…Die Aufnahme von Wasserstoff kann unter bestimmten Voraussetzungen grundsätzlich durch externe Einwirkung von atomarem oder molekularem Wasserstoff sowie durch Komponenten wasserstoffhaltiger Verbindungen (z. B. Schwefelwasserstoff) erfolgen [5]. So kann Wasserstoff an der Metalloberfläche als Folge von Korrosionsprozessen am Bauteil entstehen oder als Folge einer externen kathodische Polarisation, wie z.…”

“…Geothermal sour brines that accompany natural gas extraction commonly contain up to ∼60 mM of sulfide ion and have pH values ∼8 (Ateya and Al‐Kharafi, 2002; Sosa et al, 2002; Radkevych and Vasylenko, 2003; Krutsan et al, 2005; Galvan‐Martinez et al, 2007). They are highly toxic and odorous due to the volatilisation of hydrogen sulfide (p K a1 = 6.88, p K a2 = 14.15: Greenwood and Earnshaw, 1997).…”
