Abstract
Elemental mercury is formed in aqueous solution by the chemical reduction of mercuric ion in the presence of humic acid. The reduction proceeds via first order kinetics (rate constant, 0.009 hour-(1)) and is depndent on pH. The reaction mechanism involves interaction of the ionic metal species with the free radical electrons of the humic acid.
摘要
元素汞在水溶液中通过在腐殖酸存在下化学还原二价汞离子形成。还原过程遵循一级动力学（速率常数为 0.009 小时-(1)），并依赖于 pH 值。反应机制涉及离子金属物种与腐殖酸的自由基电子的相互作用。
