“…heavy metals), which is of importance in precision farming and in soil remediation [150,151]. Recently the analytical performance of LIBS for the determination of mercury content of soil was compared with that of another breakdown-spectroscopy method: spark-induced breakdown spectroscopy (SIBS) [152]. It was found that LIBS yields better results at higher concentrations, whereas SIBS is more suitable at lower concentrations (SIBS had a ca.…”

Laser-induced breakdown spectroscopy (LIBS) has become an established analytical atomic spectrometry technique and is valued for its very compelling set of advantageous analytical and technical characteristics. It is a rapid, versatile, non-contact technique, which is capable of providing qualitative and quantitative analytical information for practically any sample, in a virtually non-destructive way, without any substantial sample preparation. The instrumentation is simple, robust, compact, and even enables remote analysis. This review attempts to give a critical overview of the diverse progress of the field, focusing on the results of the last five years. The advancement of LIBS instrumentation and data evaluation is discussed in detail and selected results of some prominent applications are also described.

“…4, 0.75 M concentration ratio was obtained from the graph of change in fluorescence intensity to molar concentration ratio of Hg 2+ . Association constant of the compound 3-Hg 2+ complex ion was found to be K ass = 5.63×10 13 (Fig. S12, Supplementary material) using the following equation (1) [16];…”

“…Thus, the highest concentration of mercury in drinking water is set at 2 ppb by the United States Environmental Protection Agency (EPA) [10]. For the determination of mercury conventional methods are used, such as spectrophotometry, atomic absorption spectroscopy (AAS), voltammetry, surface-enhanced Raman scattering (SERS), inductively-coupled plasma mass spectrometry (ICP-MS) and high performance liquid chromotography (HPLC) [11][12][13][14]. Recently mercury has been determined with highly sensitivity and selectivity by UV-vis and fluorescence spectroscopy techniques thanks to developed sensors.…”

The hexapodal Rhodamine B derivative compound 3 containing a cyclotriphosphazene core was synthesized and characterized by spectroscopic techniques such as FT-IR, (1)H, (13)C and (31)P NMR, HR-MS, MALDI MS and microanalysis. Compound 3 is a naked eye selective sensor with colorimetric and fluorescent properties for Hg(2+) ions in the presence of other metal ions such as Na(+), K(+), Ca(2+), Ba(2+), Mg(2+), Ag(+), Mn(2+), Cu(2+), Ni(2+), Co(2+), Pb(2+), Cd(2+), Zn(2+), Fe(2+), Fe(3+), and Cr(3+). The optical sensor properties of compound 3 were investigated using UV-vis and fluorescence spectroscopy. The lowest detection limit of compound 3 was determined as 3.76 × 10(-9) M (0.75 ppb) for Hg(2+) ions. The stoichiometry of compound 3-Hg(2+) complex was found to be 1:3 (ligand/metal ion). The reusable test strip was improved by the immobilization of compound 3 into a hydrogel network. The reusability of the sensor and test strip was tested with S(2-) ion solutions.

“…Several achievements and improvements have been made in recent years, e.g. Pavan et al 9 compared two potential spectroscopic methods (LIBS and spark induced breakdown spectroscopy (SIBS)) at their optimum experimental conditions for mercury monitoring. The LOD for mercury in soil calculated using LIBS and SIBS is 483 ppm and 20 ppm, respectively.…”

The trace mercury in aqueous solution is determined by laser-induced breakdown spectroscopy (LIBS) under the assistance of solution cathode glow discharge (SCGD) system. The aqueous solution is converted to gas phase using high voltage DC discharge, and then the generated mercury vapor is cooled by gas-liquid separator to improve the concentration of mercury. Finally, a 1064 nm wavelength Nd: YAG laser is used to produce plasma. In the present experiment, the characteristic spectral line of Hg I 253.65 nm is selected for analysis, under the optimal conditions of LIBS, the influences of the acid anion, discharge current, sample flow rate and carrier gas flow rate are investigated. The temporal behavior of the electron temperature and electron number density are also investigated, the results show that the electron temperature decreases from about 10900 K to 8800 K with delay time from 200 ns to 6 μs, and the electron number density is on the orders of 10 17 and 10 18 cm -3 , and it decreases with delay time. The analytical performances of this method are evaluated under optimized conditions, the calibration curve of Hg is plotted based on the different concentrations measurement results, and the detection limit (LOD) of Hg is calculated to be 0.36 mgL -1 . By using this experimental configuration, the detection limit and sensitivity of Hg are improved to some extent. This method provides an alternative analytical method for measurement of trace mercury in water.
