Abstract
Eksprestestu metodes lietojumu cinka noteikšanā izpēte. Petkuna K., darba vadītājs Dr. chem., doc. Ģībietis J. Bakalaura darbs, 52 lappuses, 28 attēli, 28 tabulas, 38 literatūras avoti, 1 pielikums. Latviešu valodā. Darbā apkopota literatūra par cinku un to savienojumu, to īpašībām, ietekmi uz cilvēka organismu, izmantošanu. Eksperimentālajā daļā veikta cinka noteikšana ar eksprestestiem ūdens šķīdumos, veicot nolasījumus vizuāli un reflektofotometriski. Pētīta vairāku faktoru – jonu spēka, pH un dažu metālu jonu ietekme uz mērījumu rezultātiem. Fotometrija un atomabsorbcijas spektrofotometrija izmantotas kā salīdzināšanas metodes.
Study of rapid test method application in zinc detection. Petkuna K., supervisor Dr. Chem., Doc. Gibietis J. Bachelor’s thesis, 52 pages, 28 pictures, 28 tables, 38 literature sources, 1 appendix. In Latvian. The paper summarizes the literature on zinc and its compounds, their properties, their impact on the human organism, and applications. In the experimental part, determination of zinc by rapid tests (test strips) in aqueous solutions was performed by visual and reflective photometric readings. The influence of several factors - ionic strength, pH and some metal ions on the measurement results - has been studied. Photometry and atomic absorption spectrophotometry were used as comparison methods.
