Zr and U determination at trace level in simulated deep groundwater by Q ICP-MS using extraction chromatography

► The analysis of Zr and U is proposed in a simulated deep groundwater by Q ICP-MS. ► The stability of both analytes in solution was guaranteed from speciation studies. ► TRU and TODGA-based preconcentration procedures were developed. ► The methods were validated with the French AFNOR NF T90-210 standard.
