Combination of high-resolution laser-induced breakdown spectroscopy and least square method for reducing soil carbon overestimation due to iron interference

Fei Ma et al.

Summary: Laser-induced breakdown spectroscopy (LIBS) has been utilized for estimating soil carbon content by detecting atomic carbon lines, with a challenge being interference from iron lines. By using a high-resolution spectrometer, suitable emission lines near 247.8561 nm can be identified to minimize overestimation of carbon content in soil samples. This method reduces the impact of interference, soil heterogeneity, and matrix effects, showing potential for quantifying soil carbon accurately.

A Robust LG-SIMS Method for Sr Isotope Determination in Apatite Across a Wide Sr Concentration Range

Heejin Jeon et al.

Summary: This study evaluates potential interferences affecting the Sr isotope analysis of apatite by SIMS and develops a protocol for analysis and data processing that can be applied across a wide range of Sr concentrations. Despite challenges in low Sr apatite, using an empirical correction for interferences and ensuring careful control of peak shape can lead to accurate and precise measurements. A slightly positive offset in Sr-87/Sr-86 observed across different analytical conditions can also be corrected empirically, resulting in good accuracy and precision in the final corrected Sr-87/Sr-86 values.

Summary: The speciation of Pt and Rh in synthetic and natural water samples can change over time due to ageing effects, impacting their reactivity towards chelating resins. The study found that ageing had a significant impact on the uptake kinetics of these metals, with Rh showing a more pronounced effect compared to Pt. In aged spiked river water, the diffusion coefficients for Rh decreased significantly due to the formation of less soluble Rh(OH)3(s), unlike in seawater where this effect was less pronounced.
