precipitation, with additionally needed alkalinity coming from porewater (that is, a binary mixing model). Assuming thatδ13C of methyl sulphides and carbon isotope fractionation during methanogenesis are –30‰ and –60‰ (ref.44), respectively, mass balance consideration requires thatδ13C of ...
The Fe/As molar ratio of 4 was the optimal condition with an average of 93% As(III) removal based on a broad sulfate/chloride molar ratio range (1:116). However, a maximum of 96% As(III) removal was observed under the Fe/As molar ratio of 1.5 and the sulfate/chloride condition of...
