A method was described for the determination of soluble rare earth elements(SREEs)in soils by inductively coupled plasma atomic emission spectrometry(ICP AES).Separation and preconcentration of SREEs from extraction solutions of soils were achieved with MgCl 2 as a carrier at pH=10—11.The influences of pH and MgCl 2 on SREEs recovery were investigated.Matrix components of Ca 2+ ,Na +,Mg 2+ and Ac - were removed to minimize interferences and improve sensitivities.The recoveries of SREEs ar...
