Determination of ultra-trace level of 232 Th in seawater by ICP-SFMS after matrix separation and preconcentration

This article describes the development and validation of an analytical procedure for the matrix separation, preconcentration and determination of sub-ng kg levels Th in a small volume (20 mL) of seawater samples. The matrix separation and Th preconcentration was carried out using a commercially avai...

Description
Summary:This article describes the development and validation of an analytical procedure for the matrix separation, preconcentration and determination of sub-ng kg levels Th in a small volume (20 mL) of seawater samples. The matrix separation and Th preconcentration was carried out using a commercially available ion-chelation system seaFAST-pico. The acidified to pH
