Performance evaluation of packing materials in the removal of hydrogen sulphide in gas-phase biofilters: Polyurethane foam, sugarcane bagasse, and coconut fibre
(ELSEVIER SCIENCE SA, 2010)
The main objective of this work was to investigate three packing materials (polyurethane foam, sugar-cane bagasse, and coconut fibre) for biofiltration of a gaseous mixture containing hydrogen sulphide (H(2)S). Mixed ...
Biological phosphorylated molecules participate in the biomimetic and biological synthesis of cadmium sulphide quantum dots by promoting H2S release from cellular thiols
(Royal Society of Chemistry, 2017-08)
Developing methods with a low environmental impact for nanoparticle synthesis remains one of the greatest challenges in nanotechnology. In this context, biomimetic and biological methods have emerged as green chemistry ...
Hydrogen sulphide, a novel gasotransmitter involved in guard cell signalling
(Wiley, 2010-12)
•Hydrogen sulphide (H2S) has been proposed as the third gasotransmitter. In animal cells, H2S has been implicated in several physiological processes. H2S is endogenously synthesized in both animals and plants by enzymes ...
Colloidal sulphur production by electrochemical oxidation of sulphide in a swirling flow reactor
(Royal Society of Chemistry, 2021-10)
A cylindrical reactor with swirling flow is tested for the production of colloidal sulphur via the oxidation of sulphide ions with a concentration of 2 g dm−3 in alkaline solutions at 80 °C. Polysulphides are anodically ...
Can hydrogen sulphide gas be produced during alkaline leach of enargitic copper concentrates?
(Elsevier B.V., 2019)
© 2019 Elsevier B.V. The usual answer to the question stated in the title of this manuscript would be a definitive no due to the high stability of dissolved sulphide ions in water under strong alkaline conditions; nevertheless, ...
