A new preconcentration technique for the determination of the concentration and isotopic composition of neodymium in aqueous samples is presented. The method uses a resin, Nobias PA1 from Hitachi High-Technologies, which has a hydrophilic methacrylate polymer backbone where the functional groups ethylenediaminetriacetic and iminodiacetic acids are immobilized. The function of the resin has been tested by preconcentrating 110-350 pmol of Nd from test solutions as well as from natural brackish ...Expand abstract
