Environmental laboratory-environmental chemistry
Code: G570SA
Teacher:  Leonardo Scaglioni
CFU subdivision: Lectures: 3
Practices in laboratory:  3
Basic aims:  The course aims to provide the student with the knowledge of the principal aspects of chemical contamination in the different environmental compartments (water, air, soils) and the main organic and inorganic pollutants. The course introduces the analytical instrumental techniques used in environmental chemistry such as spectroscopy and chromatography. It defines the main chemical technologies related to the treatment of refusal, the site remediation and the current regulations.
Acquired skills:  The student will achieve the ability to develop and to apply methodologies for the environmental data management acquiring a suitable judgement autonomy. Must also be able to apply the acquired knowledge to the comprehension and valuation of phenomena and problems arising from the interaction between antropogenic activity and environmental matrices.
Course contents:  Measure units. Heavy metals. Environmental sampling. Spectroscopy: Ultraviolet and Visible spectroscopy. Nuclear Magnetic Resonance (NMR). Mass Spectroscopy and ICP-MS. Separation techniques: Chromatography, HPLC, GC.
Program:  Lectures (3 credits): Measure units. Heavy metals: chemistry and toxicology. Environmental sampling, samples storage. Spectroscopy: Electromagnetic radiation, Adsorption and emission spectroscopy: principles. Ultraviolet and Visible spectroscopy: Lambert Beer law, instrumentation and applications. Mass spectroscopy: theory, instrumentation, quadrupole detector, ICP-MS. Nuclear Magnetic Resonance (NMR): theory, instrumentation, chemical shift, spectra of elements other that H and C. Fundamentals of chromatography: retention time, selectivity, efficiency. Gas chromatography and HPLC, instrumentation, use in
Workshop (3 credits): Safety rules in a chemical laboratory. Sampling on the site under investigation. Sample extraction, separation by TLC and HPLC and quantification by spectrophotometric methods of plant pigments. Analysis of heavy metals and other elements by means of ICP-MS. Recording NMR spectra of different nuclei.
