Dažu elementu satura izvērtējums medū un bišu maizē. Ozoliņa Z. Darba vadītāja Dr. ķīm. Rudoviča V. Bakalaura darbs.47 lpp., 24 attēli, 5 tabulas, 38 literatūras avoti,3 pielikumi. Latviešu valodā.
Bakalaura darbā noteikts metālisko elementu saturs medus un bišu maizes paraugos, kuri ievākti dažādos Latvijas novados. Paraugu sagatavošanai izmantota sausā mineralizācija un mineralizācija 65% slāpekļskābes šķīdumā. Elementu koncentrācijas noteikšanai paraugos izmantota liesmas atomabsorbciometrija, elektrotermālā atomabsorbciometrija un liesmas fotometrija. Veikta rezultātu izvērtēšana, savstarpēji salīdzinot elementu saturu medū un bišu maizē ar literatūrā norādītajiem datiem.
Evaluation of elemental content in honey and bee bread. Ozoliņa Z. Supervisor Dr.chem. Rudoviča V. Bachelor's thesis. 47 pages, 24 illustrations, 5 tabeles,38 references, 3 attachments. In Latvian. Element content in honey and bee bread samples, which are collected in different regions of Latvia, is defined in Bachelor's thesis. Dry mineralization and mineralization in 65% in nitric acid solution is used for samples preparation. Flame atomic absorptiometry, electrothermal atomic absorptiometry and flame photometry are used for element concentration determination in samples. The result assessment has been done comparing element content in honey and bee bread according to the data presented in literature.
