文摘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.
