褐煤腐植酸对棕壤汞形态的影响
|
摘要
为探明腐植酸含量与棕壤中汞形态随时间动态变化的关系,通过室内培养试验,探讨了不同用量腐植酸对汞污染棕壤中汞赋存形态的影响。结果表明:添加腐植酸改变了棕壤中各形态汞的分配比率,使土壤水溶态、交换态、酸溶态以及残渣态汞含量降低,而碱溶态和有机结合态汞则显著增高,各形态汞与对照相比均达到显著水平(p<0.05),各形态汞在培养60 d后变化不再明显。碱溶态汞与有机结合态汞呈极显著正相关(r=0.980**),而与其他形态汞呈极显著负相关。腐植酸对棕壤汞形态的影响较大,且在一定比例范围内效果显著,各形态汞之间并非单一转化,而是多种形态之间相互转化的一种动态平衡。
In order to find out the relationship between humic acid content and the change of mercury morphology in brown soil with time,the effect of the dosage of humic acid on mercury species in polluted brown soil were explored,through the incubation experiment indoor.The results showed that adding humic acid changed the distribution ratio of various mercury in brown soil and it could decrease the contents of Ws-Hg,Ex-Hg,Aci-Hg and Res-Hg,but increased the contents of Ob-Hg and Alk-Hg remarkably,compared with no humic acid treatment various forms of mercury reached significant level( p<0.05),after sixty days various forms of mercury changed indistinctively.Between Alk-Hg and Ob-Hg existed highly significant positive correlation( r = 0.980**),but with other forms of mercury existed highly significant negative correlation.The effects of humic acid on mercury species in brown soil were larger,but in the scope of a certain proportion effects were remarkable.The various mercury forms of transformation was not a single,but there was a dynamic balance among many forms.
