Effects of a proline solution cover on the geochemical and mineralogical characteristics of high-sulfur coal gangue

Effects of dissolved organic matter derived from cow manure on heavy metal(loid)s and bacterial community dynamics in mercury-thallium mining waste slag

“…The degree of the effect of DOM on the pH, EC, and Eh values and SO 4 2− content in the leachate signi cantly increased with increasing DOM content. Additionally, the Eh and EC values and SO 4 2− content in the same DOM content treatment increased with increasing incubation time, but the pH showed the opposite trend.The increased pH of leachate in the presence of DOM may be due to the DOM buffering effect on leachate pH(Luo et al, 2018a). The Eh of leachate in the presence of DOM signi cantly decreased, and the Eh was the lowest when DOM was added in the maximum amount, which indicated that DOM rich in organic matter decomposition could consume oxygen in the leachate(Beauchemin et al, 2018;…”
