Removal of hydrogen sulfide gas using coal fly ash – blast furnace cement composite

Journal of Water, Sanitation and Hygiene for Development, 2021
The number of complaints regarding offensive odors from service industries, such as restaurants and garages, has recently increased. In this study, we aimed to develop an adsorbent for hydrogen sulfide gas derived from domestic wastewater and reveal the ...

A new purple sulfur bacterium from saline littoral sediments, Thiorhodotvibrio winogradskyi gen. nov. and sp. nov. [PDF]

, 1992
Two strains of a new purple sulfur bacterium were isolated in pure culture from the littoral sediment of a saline lake (Mahoney Lake, Canada) and a marine microbial mat from the North Sea island of Mellum, respectively.

Biology and therapeutic potential of hydrogen sulfide and hydrogen sulfide-releasing chimeras [PDF]

Biochemical Pharmacology, 2013
Hydrogen sulfide, H2S, is a colorless gas with a strong odor that until recently was only considered to be a toxic environmental pollutant with little or no physiological significance. However, the past few years have demonstrated its role in many biological systems and it is becoming increasingly clear that H2S is likely to join nitric oxide (NO) and ...

A kinetic and theoretical study of the borate catalysed reactions of hydrogen peroxide: the role of dioxaborirane as the catalytic intermediate for a wide range of substrates [PDF]

, 2012
Our recent work has provided new insights into the equilibria and species that exist in aqueous solution at different pHs for the boric acid – hydrogen peroxide system, and the role of these species in oxidation reactions. Most recently, (M. C.

Hydrogen microsensors with hydrogen sulfide traps

Sensors and Actuators B: Chemical, 2015
AbstractHydrogen is often formed in sulfidic environments where interference from hydrogen sulfide has prevented its analysis by amperometric hydrogen microsensors. Hydrogen microsensors were made insensitive to hydrogen sulfide by placing a sulfide trap (guard) containing solutions of heavy metal ions, sulfide-oxidizing ferricyanide, or alkaline ...

STUDY OF HYDROGEN SULFIDE REMOVAL FROM GROUNDWATER [PDF]

Chemistry Journal of Moldova: General, Industrial and Ecological Chemistry, 2013
The process of the hydrogen sulfide removal from the underground water of the Hancesti town has been investigated. By oxygen bubbling through the water containing hydrogen sulfide, from the Hancesti well tube, sulfur is deposited in the porous structure ...

SEX DIFFERENCES IN THE INFLUENCE OF HYPERHOMOCYSTEINEMIA ON HYDROGEN SULFIDE METABOLISM IN THE CARDIOVASCULAR SYSTEM

Vіsnik Naukovih Doslіdžen', 2017
Hyperhomocysteinemia is a well-known and independent risk factor of heart and blood vessels diseases. It is shown that this pathological condition decreases the level of hydrogen sulfide – which is a biologically active substance that is involved in the ...

Poly(1,4‐anthraquinone) as an Organic Electrode Material: Interplay of the Electronic and Structural Properties due to the Unusual Lone‐Pair‐π Conjugation

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
In this study, the unique role of the unusual lone‐pair‐π conjugation mechanism in poly(1,4‐anthraquinone) (P14AQ) is explored as an organic electrode material. Unlike traditional π‐π interactions, P14AQ's conjugation involves lone pairs of oxygen atoms interacting with the π cloud of adjacent units, enabling stable charge transport even with minimal π‐

Non-enzymatic hydrogen sulfide production from cysteine in blood is catalyzed by iron and vitamin B6

Communications Biology, 2019
Hydrogen sulfide (H2S) plays important roles in metabolism and health. Its enzymatic generation from sulfur-containing amino acids (SAAs) is well characterized. However, the existence of non-enzymatic H2S production from SAAs, the chemical mechanism, and
