Fe(OH)3 co-precipitation aerosol dilution ICP-MS method developed for REE analysis
Over 93% of matrix elements were removed by the Fe(OH)3 co-precipitation procedure.
The target REEs were concentrated 15-fold by this precipitation procedure.
Online aerosol dilution technique decreased the rates of interfered oxide by up to 10-fold.
The residual matrix effects were effectively reduced by this dilution technique.
