摘要
在（ＣＨ２）６Ｎ４－ＨＣｌ底液中，以ＨＴＴＡ／ＴＯＰＯ混合物为修饰剂修饰于钨丝电极，经电解预富集后用石墨炉原子吸收法进行镱（Ｙｂ）的测定。应用本法可使Ｙｂ的检出限达到００２９μｇ／Ｌ，比文献报道值大为降低。
A tungsten filament electrode decorated with a mixture of tri-n-octyl phosphine oxide (TOPO) and 2-thenoyl trifluoroacetone (HTTA) was used in direct atomization measument of Yb,When the electrode was put in to pyrolysis in coated granhite cup (PGC).The detection limit (CL)for Yb was 0.029g/l, and was much lower than the reported value. the interference coming from rare earth metals am reduced notably.
