• Abstract

  The occurrence of organic (e.g., agrochemicals, aromatics, polychlorinated biphenyls) and inorganic (e.g., Cd, Pb, Hg, As) pollutants in the environment has stimulated the need to monitor the levels of these species in order to promote the environmental and food safeties. Solid phase extraction (SPE) methods are the most used strategy for sample preparation for the analysis of these pollu…

• Abstract

  The aim of this project is to use new polymeric materials aiming at the concentration and separation of rare earth elements (La, Ce and Nd) from waters for further determination by determination by inductively coupled plasma optical emission spectrometry (ICP OES) and inductively coupled plasma mass spectrometry (ICP-MS). Polysaccharides based substrates, such as cellulose, xanthan and al…

• Abstract

  For many decades, the accurate and precise determination of isotope ratio has remained a very strong interest to many researchers due to its important applications in environmental, geological, biological, archeological, and medical sciences. Isotope analysis of groundwater intended for human consumption can provide valuable information on the processes of transfer of elements within envi…

• Abstract

  Systematic studies dealing with analysis of plant materials by laser-induced breakdown spectroscopy (LIBS) with different lasers are still necessary, and one would expect that matrix effects could be minimized by using either nanosecond lasers at UV or femtosecond lasers, which generally provide ablation processes less dependent on physical and chemical properties of the matrix. The aim o…
