摘要: Abstract Direct current plasma atomic emission spectrometry (DCP-AES) was used for the determination of cerium, europium and terbium in rare earth matrices. The interference effect matrix elements phosphors (yttrium, lanthanum, gadolinium lutetium) vanadium, phosphorus, sulphur, boron, silicon, aluminium, magnesium barium investigated. Considerable spectral interferences from were found at most lines studied. other studied caused only minor interference. By using suitable (418.66 nm 282.08 332.44 terbium), can be determined yttrium, lutetium matrices, but some cases use a background compensator is necessary.
