✦ Synopsis

An mductlvely coupled plasma atomic emlsslon spectrometrlc WP-AES) method for the determmatlon of lanthamdes and yttrmm m rare earth ores and concentrates 1s described After a smtable separation of these elements from the other matru( constituents, a mtnc solution of rare earth elements was obtained for the ICP-AES measurements

The optunum condltlons were selected by a simplex method Several analytlcal wavelengths were chosen for each element, using barmm as mtemal standard A detaded study of spectral interferences was made and correctlon coefficients were calculated Good agreement between the results and previously published values obtamed by several techmques was obtamed
