Abstract: Abstract The previously unknown arsenic-containing triacylglycerides (AsTAGs) 3-((15-(dimethylarsinoyl)pentadecanoyl)oxy)propane-1,2-diyl dipalmitate 1 and 2-((15-(dimethylarsinoyl)pentadecanoyl)oxy)propane-1,3-diyl dipalmitate 2 have been synthesized. They will serve as model compounds in the search for naturally occurring AsTAGs, recently proposed natural constituents of… read more here.

DOI: 10.3390/su17062359
Abstract: Herein, targeting arsenic-containing acidic wastewater generated from washing arsenic-containing flue gas with concentrated sulfuric acid, the arsenic removal efficiency using H2S was investigated. The effects of H2S concentration, the gas flow rate, H2SO4 concentration, temperature,… read more here.
