“…Lazic et al [27], Barbini et al [28] and Lazic et al [29] used LIBS for the determination of Cr, Cu, Mn, Fe, Ba and other metals in marine sediment samples. Similarly, Mohamed and Askar [30], Capitelli et al [31], Santos et al [32] and Senesi et al [33] determined heavy metals (V, Cr, Mn, Fe, Ni, Co, Cu, Zn, Pb and Cd) in soil and sediment using LIBS.…”

ABSTRACT. In the present study, laser-induced breakdown spectroscopy (LIBS) has been applied for the determination of levels of Cr, Mn and Fe in sediment samples and the results have been compared with that of flame-atomic absorption spectroscopy (F-AAS). Fourteen sediment samples were collected from Tinishu Akaki River (TAR), Addis Ababa, Ethiopia. Pellets of 24 mm in diameter and 3−5 mm in thickness were prepared using a manual hydraulic press under a pressure of 8000 psi by mixing finely ground sediment samples with boric acid. The concentrations of Cr, Mn and Fe were successfully determined by Q-switched Nd:YAG laser at 1064 nm. Quantification of these metals was conducted against certified reference materials of sediments and soils. The LIBS results for the elements varied from 0.060-0.707 mg/g for Cr, 0.895-3.64 mg/g for Mn and 26.9-71.8 mg/g for Fe. The F-AAS results varied from 0.061-1.37 mg/g for Cr, 1.24-4.46 mg/g for Mn and 49.0-83.3 mg/g for Fe. TAR was found to be heavily polluted with Cr.

“…The application of LIBS to soil [6,[24][25][26][27][33][34][35][36] and sediment [22,37,38] analyses has been of growing interest during the last decade. The LIBS technique has been mainly applied to solve two related problems of soil analysis.…”

ABSTRACT. Laser-induced breakdown spectroscopy (LIBS) is an emerging analytical technique, which can be used to perform elemental analysis of any material, irrespective of its physical state. In this study, the LIBS technique has been applied for quantification of total Cr in soil samples collected from polluted areas of Brits, North West Province, South Africa. A Q-switched neodymium-yttrium aluminium garnet (Nd-YAG) laser (10 Hz, λ = 1064 nm) was employed for generation of a laser-induced plasma on the surface of the soil sample. The atomic emission lines were recorded using an Andor Shamrock SR-303i spectrometer, fitted with an intensified charge-coupled device (ICCD) camera. Detailed investigation of experimental parameters such as gate delay time, gate width and laser pulse energy was conducted. Soil samples were dried, finely ground, sieved and thereafter pelletized before LIBS analysis. Calibration curve for the quantification of Cr was constructed using certified reference materials of soils and sediments. The concentrations of Cr in soil samples varied from 111 to 3180 mg/kg. In order to test the validity of the LIBS results, inductively coupled plasma-mass spectrometry (ICP-MS) was also employed for determination of Cr. The results obtained using LIBS were found to be in good agreement with those of ICP-MS.

“…It is contrary to the concept of green analytical chemistry, and solid sample preparation appears to be more preferable from this point of view. X-ray fluorescence, [8][9][10] neutron activation analysis, 11,12 and laser induced breakdown spectroscopy 6,13,14 are applied for direct analysis of soil in the form of pellets or powders. However, these methods are used not as often as ICP-AES due to the considerable matrix effects and require the calibration samples similar to the analyzed ones.…”

“…To extract elements from soil into solution, sample digestion in different acid mixtures composed of HF, HCl, HNO3, HClO4, and H2O2 is applied. [3][4][5][6] Complex matrix composition of soils often complicates trace element determinations due to spectral interferences. To exclude spectral overlapping, Picoloto et al 7 developed a method for As, Cd, Hg and Pb volatilization from soil using microwave-induced combustion.…”

The possibility of direct analysis of soils by two-jet plasma atomic emission spectrometry was investigated using certified reference materials of black earth, grey desert and red soils. It was shown that As, B, Cd, Cu, Hg, P, and V could be determined after a 2-fold, and Be, Co, Cr, Ga, Nb, Pb, and Zn-after a 10-fold dilution of the samples by a spectroscopic buffer using calibration samples based on graphite powder. The strongest matrix effects were revealed for red soil having the highest Al and Fe concentration, which led to the overstated concentrations of some elements. The overstating factor depended on analyte concentration and was no more than 2. A clear advantage of the suggested technique over existing methods is the simple sample preparation process, which requires no reagents except a spectroscopic buffer, and possibility of using the same calibration samples for analysis of different soils.
