用连续化学浸提法将施用了不同量氯化汞的盆栽土壤中的汞,按其形态分为水溶态及交换态、酸溶态、碱溶态、元素态、残渣态等五个组分,实验结果表明,氯化汞进入不同类型和质地的土壤后,一半以上转化为残渣态,而水溶态和交换态以及酸溶态的甲基态都很少,其他形态在土壤中也占有一定的比例。在不同的土壤中,各种形态汞的分布有所不同;但对同一种土壤来说,汞的形态分布顺序与施汞量无关。
The mercury in potted soil applied with different amount of mercuric chloride by continuous chemical leaching method was divided into five parts according to their morphology: water soluble and exchangeable, acid soluble, alkali soluble, elemental and residual The experimental results show that more than half of the mercuric chloride is transformed into the residue state when it enters the soil of different types and textures while the methyl state of the water-soluble and exchangeable and acid-soluble states is very little and the other forms also occupy a certain amount in the soil proportion. In different soils, the distribution of various forms of mercury is different; however, the order of the distribution of mercury is not related to the amount of mercury applied to the same soil.
