Abstract

The combination of ultrasound-assisted dispersive micro solid-phase extraction (USA DMSPE), with the use of silver nanoparticles (AgNPs) as a solid sorbent, with high-resolution continuum source electrothermal atomic absorption spectrometry (HR-CS ETAAS) is proposed for the preconcentration and determination of Hg2+ ions in water samples. The main extraction and detection parameters were investigated. Effective preconcentration of trace mercury was achieved at pH 3.5 with 10 mg of AgNPs. Amalgamated mercury was dissolved in 200 mu L of 7 mol L-1 HNO3 before atomic absorption spectrometry (AAS) detection. The concentration limit of detection was 0.005 ng mL(-1). The achieved preconcentration factor was 15 and the relative standard deviations (RSDs, %) for real water samples were 6-11%. The accuracy of this method was evaluated by analyses of CRMs. The method has been successfully applied to the determination of mercury in three different real water samples.

Spatio-temporal dynamics of a microsecond pulsed Grimm-type glow discharge

Ivan B. Krstic, Bratislav M. Obradovic, Milorad M. Kuraica

Summary: This paper presents the spatio-temporal dynamics of a Grimm-type microsecond pulsed glow discharge (mu PGD) in argon at 6 mbar. The occurrence of a high current peak during the discharge ignition is analyzed and the importance of displacement current is emphasized. The development of electron excitation temperature for argon atoms and ions at various distances from the cathode is measured. The spatio-temporal evolution of selected spectral lines of argon and copper atoms and ions is analyzed during different phases of the discharge. The results suggest that the behavior of spectral line emissions differs between the pre-peak and afterglow periods, with different lines reaching maximum intensity during these phases. The appearance time and decay time of the afterpeak are shorter for ions than for atoms. These findings are explained in terms of three-body recombination processes and ion mobilities.

Sensitivity improvement of laser-induced breakdown spectroscopy to detect heavy metals in water by Tesla coil discharge

Qiuyun Wang, Anmin Chen, Xun Gao

Summary: In this paper, the combination of Tesla coil discharge (TCD) and laser-induced breakdown spectroscopy (LIBS) was used to enhance the emission of Al atomic lines and AlO molecular bands. The optimized distance between the TCD tip and the sample surface was found to be 5 mm, and the optimal laser energy was 25.1 mJ. Furthermore, TCD-SELIBS showed lower limits of detection (LoDs) for Cr and Pb elements compared to surface enhanced LIBS (SELIBS). The combination of TCD and LIBS is a promising technology for high-sensitivity analysis of heavy metals in water, with the advantages of simplicity, low cost, ease of operation, industrialization, and commercialization.

A new appraisal of ilmenite U-Pb dating method by LA-SF-ICP-MS

Yanwen Tang, Tingguang Lan, Jianfeng Gao, Zhongjie Bai, Xiaowen Huang, Junjie Han, Na Liu

Summary: Titanium is an important metal widely used in various industries. Ilmenite minerals are the main source of titanium metal and can be found in igneous and metamorphic rocks as well as different types of deposits. To accurately determine U-Pb ages of ilmenite, a new calibration method and appropriate reference materials are urgently needed. Laser ablation sector field inductively coupled plasma mass spectrometry has been used to minimize matrix effects and zircon 91500 has been identified as a suitable reference material for measuring the Pb/U ratio in ilmenite. The direct calibration method using zircon 91500 as an external standard has been found to be effective for in situ U-Pb dating of ilmenite samples under different ablation settings.
