Summary: Nitrous oxide (N2O) was investigated as a reaction gas for the determination of rare earth elements (REEs) by inductively coupled plasma-tandem quadrupole mass spectrometry (ICP-QMS/QMS). The use of N2O as the reaction gas improved the yields of (MO+)-M-m-O-16 for Eu and Yb, resulting in improved sensitivities for measurement of Eu and Yb. The use of N2O as the reaction gas also helped suppress Ba-related spectral interferences with the measurement of Eu. The method was validated by determining REEs in certified reference materials.

Summary: The measurement of Pb-204-based isotopic ratios by quadrupole ICP-MS was investigated and optimized. The internal precision of the isotopic ratios reached about 0.4% at a Pb concentration of 1 μg L-1 and about 0.2% at 10 μg L-1, similar to the values reported for major isotopes measurements. The developed method was demonstrated to be applicable in the environmental field and produced data in good agreement with the isotopic composition of airborne particulate in central Greenland.

Wheat and barley showed different responses to bromide contamination, with barley accumulating higher concentrations of bromine and demonstrating lower pigment concentrations in leaves. Despite initially lower biomass in contaminated soil, bromides ultimately had a positive effect on plant growth.

Optimizing plasma parameters improved sensitivity, and using gold as an internal standard led to improved accuracy and reproducibility of results. Calibration standards should be as similar as possible to the sample matrix due to strong matrix effects.

Summary: Xanthates, commonly used collectors in flotation processes, have high toxicity to the aquatic environment. However, there are limited methods for accurately determining low concentrations of xanthates in water samples. This study presents a sensitive, selective, and fast method for determining potassium ethyl xanthate (KEX) using high-performance liquid chromatography-inductively coupled plasma-mass spectrometry (HPLC-ICP-MS/MS). The method was optimized for diethyl dixanthogen [(EX)(2)] and showed potential for analyzing other xanthates and collectors with similar structures.

Summary: Characterizing Zr-containing dispersoids in aluminum alloys is challenging due to their diverse size distribution, low volume fraction, and uneven distribution within the grains. This study compared small-angle X-ray scattering (SAXS) and small-angle neutron scattering (SANS) with scanning electron microscopy (SEM) and transmission electron microscopy (TEM) in characterizing Zr-containing dispersoids. Both scattering techniques were found suitable for characterizing dispersoids in a multi-phase industrial 7xxx series aluminum alloy. SAXS was more sensitive than SANS due to the high electron density of Zr-containing dispersoids, while SANS had the advantage of probing a larger sample volume. The combination of both techniques allowed for distinguishing the contribution of dispersoids from other precipitate phases.

Summary: The aim of this study is to investigate the petrochemical characteristics of rocks and determine the relationship between the distribution of porphyry copper mineralization and the tectonic position of faults. The results show that the rocks of the Astaneh ore deposit were formed in the suprasubduction zone and the mineralization process can be divided into three stages. The tectonomagmatic phases of the development of the Neotethys Ocean have a high spatio-temporal similarity with the main stages of the formation of the porphyry copper ore deposit in the study area.

Summary: The present study introduces a new and selective analysis method for determining low xanthate concentrations. This study addresses the growing concern over the environmental impact of xanthates and the need for reliable analysis methods. The method utilizes the complex formation between xanthates and various metal ions in aqueous solution, followed by liquid-liquid extraction and high-performance liquid chromatography, to accurately determine xanthates. By using Cu(II) as the complex metal ion, good separation and high measurement sensitivity are achieved. The method has been optimized for sodium isopropyl xanthate and sodium isobutyl xanthate, with detection limits of 24.7 μg/L and 13.3 μg/L, respectively. With a linear calibration range of 0.1-15 mg/L and a total analysis time of 4-5 min, this method offers a fast and sensitive option for selective xanthate determination.

Summary: In the Zn/Cd hyperaccumulator Noccaea caerulescens plants, high concentrations of Zn and Cd treatment enhance resistance against Turnip yellow mosaic virus (TYMV). RNAseq analysis showed TYMV-induced upregulation of Ca transporters, chloroplastic ZTP29, and defense genes in N. caerulescens. Unlike N. ochroleucum, Zn hyperaccumulation in N. caerulescens remains strongest regardless of TYMV infection.
