Description
Summary:•Lanthanoids as geochemical tracers in seawater.•A 4-step strict protocol and state-of-the-art technology for lanthanoids analyses in seawaters.•Sample pre-concentration system for matrix separation for the detection of ultra-low lanthanoids levels. Analysis of lanthanoids in seawater is challenging due to the complex matrix (∼35 g L−1 TDS) and low dissolved concentrations (in ng L−1). A 4-step strict analytical protocol and state-of-the-art technology were implemented and validated in this study. The 4-steps method involves the 1) sample filtration and acidification (pH
