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.

“…This method is used in agricultural chemistry to determine the soil content of carbon, which characterizes the humus content, and several nutritious elements and toxins [14][15][16]. For this, LIBS factors such as simple sample preparation for analysis, rapid processing of results and their distribution, and prospects for determining the soil composition under field conditions are important [17].Because soil has a complicated background composition, it is analyzed as a rule by calibrating instruments using certified samples (standards). These standards can differ in complexity even for solving similar problems depending on the matrix of samples subject to analysis.…”

The application of laser spectrochemical analysis to testing for basic compounds and nutritious/toxic elements in soil has been reviewed. A combined laser-spark approach has been applied for the rapid measurement of the carbon content in soil. Spectra have been excited both directly in a laser-ablation plume and by passing a pulsed electric discharge through the plume. The emission spectrum intensity in the combined plasma is considerably higher. The application of a complex of methods to carbon determination in soil has shown that in fact the data on the humus content usually obtained in agrochemical practice by a conventional method of carbon oxidation by potassium dichromate need to be corrected taking into account the possibility of incomplete oxidation of organic matter in soil. The efficiency of various double-pulse LIBS applications has been demonstrated in solving a number of environmental problems such as the determination of heavy and toxic metals in soil and the detection of sulfur in coal. The instrumentation and analytical procedures have been proposed and optimized for rapid control of the chlorine content in plant samples. The technique can be easily extended to ecological monitoring of toxic elements and heavy metals in any biogenic material.Introduction. Laser methods for analyzing the composition of soil, ore, minerals, and related materials have been developing rapidly for the last decade. A comprehensive review of these methods reveals that the technology for performing the analytical procedures, the equipment, and the techniques for processing results are similar. The employed methods are based on emission spectroscopy, fluorescence, Raman scattering, IR reflectance from the samples, etc. Laser-induced breakdown spectroscopy (LIBS) is promoted as a primary technique. This method was developed very early [1-4] and is sufficiently validated for solving various practical problems such as quality control of industrial products [5], processes [6], the environmental situation [7], water resources [8], and the composition of ores and minerals [9] in addition to problems in criminology for detecting explosives [10], pharmacology [11], archeology and art [12], and biological samples [13]. This method is used in agricultural chemistry to determine the soil content of carbon, which characterizes the humus content, and several nutritious elements and toxins [14][15][16]. For this, LIBS factors such as simple sample preparation for analysis, rapid processing of results and their distribution, and prospects for determining the soil composition under field conditions are important [17].Because soil has a complicated background composition, it is analyzed as a rule by calibrating instruments using certified samples (standards). These standards can differ in complexity even for solving similar problems depending on the matrix of samples subject to analysis. For example, the determination of C in chernozem and loamy soils and rocky and peaty ores cannot be carried out using single certified samples. Standards ...
