| 摘 要： | 对广州泌冲地区土壤中的稀土元素进行了模拟酸雨淋溶实验研究。结果表明，模拟酸雨对土壤中稀土元素溶出量的影响显著．酸雨的pH值越低，硫酸根离子浓度越高，稀土元素的溶出量越大，其变化幅度为8．98％-11．95％．轻稀土元素的溶出量大于重稀土元素．

| Abstract: | A leaching process is studied for REE solubility in soils from Bichong,Guangzhou acted by imitated acid-rain.Experimental results show that the effect of imitated acid-rain on REE mobility and migration in the soil is enormus.The lower pH value and higer SO 2- 4 content in imitated acid-rain is,the larger REE solubility amount the soil possesses,with the range from 8.98% to 11.95%.The solubility amount of LREE is larger than that of HREE in soils. |
