【摘要】 采用吸附 解吸热力学和动力学方法研究了腐殖酸各组份对土壤吸持汞的影响 ,发现该试验条件下 ,腐殖酸能提高土壤对汞吸持能力 ,但不同组份其作用效果不同 ,富里酸在提高土壤吸持汞方面作用较短暂且不稳定 ,胡敏酸在增强土壤吸附固定汞的数量和速率上却好于富里酸。更多还原

【Abstract】 The effect of humus on mercury adsorption in soil was assessed in thermodynamic experiment of adsorption and desorption. HAs was found to efficiently improve Hg adsorption ability while FA only plays an unsteady role. HA could improve soil Hg to be adsorbed gradually and constantly.更多还原
