Janja Kristl (Author), Mitja Kolar (Reviewer), Tomaž Langerholc (Reviewer)

Abstract

Navodila za vaje dopolnjujejo nekatere vsebinske sklope predavanj pri predmetih Kemijske analitične metode v kmetijsvtu in Toksične snovi v ekosistemih. Študentu pomagajo razumeti posamezne pojme (ekstrakcija, atomska absorpcijska spektrometrija, molekulska absorpcijska spektrometrija, tekočinska kromatografija, kislinski razklop) in laboratorijske postopke. V gradivu so opisani postopki priprave vzorcev in kvantitativne določitve natrijevega klorida, proteinov, skupnih fenolov, sladkorjev, oksalatov, vodikovega cianida v vzorcih živil in žveplovega dioksida v vinu. Vključena je tudi kvalitativna določitev nitrata in nitrita v ekstraktih živil ter kvalitativni testi za ugotavljanje prisotnosti naravnih in sintetičnih barvil. Vsebina zajema tudi določitev rastlinam dostopnega bakra ter vodotopne in biodostopne frakcije svinca v talnih vzorcih.

Secondary title:	Chemical Analytical Methods in Agriculture and Toxic Compounds in Ecosystems
Secondary abstract:	Instructions for laboratory exercises support some of the content of the lectures in Chemical Analytical Methods in Agriculture and Ecotoxicology. They help students understand some terms (extraction, atomic absorption spectrometry, molecular absorption spectrometry, liquid chromatography, acid digestion) and laboratory procedures. The manual describes the procedures for sample preparation and quantitative determination of sodium chloride, proteins, total phenols, sugars, oxalates, hydrocyanic acid in food samples, and sulfur dioxide in wine. The qualitative determination of nitrate and nitrite in food extracts and qualitative tests for the detection of natural and synthetic pigments are also included. The content also includes the determination of plant-available copper and the water-soluble and bioavailable lead fraction in soil samples.
