| 摘 要： | 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。棕色胡敏酸参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的以及矿物与腐殖酸的作用特性密切相关。

| Abstract: | Experimental results indicated that fulvic acid can significantly promote the volatilization of MnO2-Hg,Fe2O3-Hg and kaolinite-Hg, but suppress that of bentonite-Hg and CaCO3-Hg. Generally brown humic acid can enhance the volatilization of all the mineral-bound Hg except for Fe2O3-Hg. The effect of grey humic acid is the weakest. The influence of humus fractions on the activity of mineral-bound Hg is dependent on the complex capacity and complex stability of humus fractions with Hg, adsorption capacity and adsorption strength of the mineral with Hg as well as the interaction characteristics between humus fractions and minerals. |
