✦ Synopsis

An on-line preconcentratlon system Implemented urlth mductlvely coupled plasma atonuc emlssmn spectrometry (ICP-AES) was studled For the retention of metal Ions 8-hydroxyqumohne and Amberhte XAD-2 resm were used Tlus system Improved the detectIon lmuts of Cd, Cu, Fe, Mn, NI and Zn by a factor of 100 compared urlth ICP-AES alone Owmg to tins senslhvlty and the excellent selectmty towards the transItIon metal Ions with respect to salt matnces, the method was successfully apphed to the determmatlon of the above metals m AntarctIc sea water The concentration found ranged between 16 ng 1 -' (Mn) and 0 4 pg 1-l (NI) wth a precision of 10%
