挥发试验结果表明,试验条件下,富里酸能极显著地促进Fe2O3-Hg,MnO2-Hg与高岭土结合汞的挥发,对膨润土结合汞和碳酸钙结合汞的挥发则表现抑制作用。棕色胡敏酸能促进各矿物结合汞的挥发。灰色胡敏酸影响最为微弱。腐殖酸对矿物结合态汞挥发性的影响与其对汞的络合容量与络合稳定性,矿物对汞的吸持特性,以及矿物与腐殖酸的作用特性密切相关。
Volatilization test results show that under the experimental conditions, fulvic acid can significantly promote the volatilization of mercury combined with Fe2O3-Hg, MnO2-Hg and kaolinite, and inhibit the volatilization of mercury combined with bentonite and calcium carbonate. Brown humic acid can promote the volatilization of various minerals combined with mercury. Gray humic acid has the weakest effect. The effect of humic acid on the volatility of mineral-bound mercury is closely related to the complexation capacity and complexation stability of mercury, the adsorption and desorption of mercury by minerals, and the interaction between minerals and humic acid.
