Abstract
Ovaj diplomski rad sastoji se od dvije cjeline: istraživačkog i metodičkog dijela. U prvom dijelu proučavana je reakcija između rutenija(III) i 5-sulfosalicilne kiseline spektrofluorimetrijskom metodom. Rutenij(III) snažno gasi fluorescenciju 5-sulfosalicilne kiseline u neutralnim otopinama pri pH = 7,3 (kontrolirano fosfatnim puferom) uz konstantnu ionsku jakost μ = 0,02 mol dm−3 (održavana pomoću otopine NaCl). Fluorimetrijska mjerenja provedena su pri λem / λex = 401 / 235 nm te λem / λex = 401 / 297 nm. Smanjenje intenziteta fluorescencije proporcionalno je koncentraciji rutenija(III) u području od 0,2 do 12,1 μg cm−3, ako je koncentracija 5-sulfosalicilne kiseline 3✕10−5 mol dm−3, korelacijski koeficijent iznosi 0,995. U metodičkom dijelu rada pod naslovom Timsko poučavanje u nastavi kemije – fluorescencija naveden je prijedlog pripreme nastavnog sata kojeg zajedno provode nastavnici fizike, kemije i biologije, primjeren učenicima četvrtog razreda gimnazije. Predloženi su jednostavni pokusi za koje je detaljno razrađen radni listić za učenike i uputa za nastavnike.
Abstract (english)
This Diploma thesis consist of two parts: the research part and the methodological part. In the research part the interaction between 5-sulfosalicylic acid (5-SSA) and ruthenium(III) was investigated by the spectrofluorimetric method. Ruthenium(III) can effectivelly quench the fluorescence of 5-sulfosalicilyc acid in a neutral medium pH = 7.3 (maintained by phosphate buffer) at constant ionic strange μ = 0.02 mol dm−3 (maintained by solution of NaCl). The fluorimetric measurements were conducted at λem / λex = 401 / 235 nm and at λem / λex = 401 / 297 nm. The calibration graph was linear over the range 0.2-12,1 μg cm-3 of ruthenium, if the concentration of 5-sulfosalicylic acid was 3✕10−5 mol dm−3 with a correlation coefficient of 0.995. The methodological part of the Thesis entitled Team teaching in chemistry − fluorescence comprises a proposal of a preparation plan of a teaching lesson appropriate to students of the fourth grade of high school, carried out together by teachers of physics, chemistry and biology. Simple experiments are proposed, with detailed worksheets for students and guidance for teachers.
