“…Results proved that this MSFIA-LOV-ICP-MS method can be used to determine concentrations of lead and strontium in a wide concentration range including trace levels with a high and remarkable reproducibility, together with low consumption of Sr-resin, long lifetime of the column, and good recoveries. In addition, different stages of elution were avoided and the cleanup of the sample was carried out in a single step in comparison with previously developed methods in which Sr-resin was also exploited for the isolation of lead and strontium. ,− Ammonium oxalate had been previously reported in bibliography for lead elution and experimentally, we found that both Sr and Pb can be simultaneously eluted avoiding separation steps when exploiting a selective detector, such as ICP-MS.…”

A new automated, sensitive, and fast system for the simultaneous online isolation and preconcentration of lead and strontium by sorption on a microcolumn packed with Sr-resin using an inductively coupled plasma mass spectrometry (ICP-MS) detector was developed, hyphenating lab-on-valve (LOV) and multisyringe flow injection analysis (MSFIA). Pb and Sr are directly retained on the sorbent column and eluted with a solution of 0.05 mol L–1 ammonium oxalate. The detection limits achieved were 0.04 ng for lead and 0.03 ng for strontium. Mass calibration curves were used since the proposed system allows the use of different sample volumes for preconcentration. Mass linear working ranges were between 0.13 and 50 ng and 0.1 and 50 ng for lead and strontium, respectively. The repeatability of the method, expressed as RSD, was 2.1% and 2.7% for Pb and Sr, respectively. Environmental samples such as rainwater and airborne particulate (PM10) filters as well as a certified reference material SLRS-4 (river water) were satisfactorily analyzed obtaining recoveries between 90 and 110% for both elements. The main features of the LOV-MSFIA-ICP-MS system proposed are the capability to renew solid phase extraction at will in a fully automated way, the remarkable stability of the column which can be reused up to 160 times, and the potential to perform isotopic analysis.

“…For the preconcentration of 90 Sr in seawater, carbonate coprecipitation (Noshkin and Mott, 1967;Sugihara et al, 1959), oxalate precipitation (Bojanowski and Knapinska-Skiba, 1990), and cation exchange chromatography (Grahek and Rožmarić Mačefat, 2005) were applied. Carbonate precipitation is the most widely used method for preconcentration because it allows Sr to be collected quantitatively.…”

90 Sr released into seawater from nuclear bomb testing and nuclear facility accident sites requires long-term monitoring. However, measuring 90 Sr in seawater is still difficult and time-consuming. This study is aimed at improving the preconcentration method for successive purification using DGA Resin chromatography, which is applied to 90 Sr analysis in seawater. At natural pH, the oxalate coprecipitation technique effectively collected Sr (84% in Sr yield) from seawater without Mg or Na. For 90 Sr determination, 90 Y in secular equilibrium with 90 Sr was directly extracted using Fe coprecipitation and DGA Resin chromatography. The proposed method simplifies the analytical processes associated with the conventional method. Analytical results for surface seawater in the western North Pacific (0.81 ± 0.06 Bq m-3 , n = 5) were consistent with those obtained using the conventional method (0.81 ± 0.07 Bq m-3 , n = 5).
