摘要/Abstract

Abstract: A leaching process is studied for REE solubility in soils from BichongGuangzhou acted by imitated acidrain．Experimental results show that the effect of imitated acid－rain on REE mobility and migration in the soil is enormous．The lower pH value and higer SO2－4content in imitated acid－rain isthe larger REE solubility amount the soil possesseswith the range from8．98％ to11．95％．The solubility amount of LREE is larger than that of HREE in soils．

Key words: rare earth element, imitated acid－rain, leaching
