Abstract
Minijaturizacijom kapilarne elektroforeze nastala je elektroforeza na mikročipu. Separacija nabijenih vrsta odvija se u separacijskom mikrokanalu pod utjecajem električnog polja. Cilj ovog rada je ispitivanje mogućnosti separacije kalija u dijetetskim suplementima elektroforezom na mikročipu. Dijetetski suplementi su dodaci prehrani koji su spravljeni od koncentriranih izvora hranjivih tvari. Zbog njihove sve lakše dostupnosti na tržištu i povećanja broja potrošača, pojavila se potreba za njihovom preciznom analizom. U prikazanom radu ispitana je mogućnost detekcije i separacije kalija u dijetetskim suplementima. Za detekciju je korišten C4D detektor, a kao pozadinski elektrolit octena kiselina kiselina (c = 0,5 mol/dm3). Uz pomoć linearne regresijske analize utvrđen je linearni odziv. Metodički dio rada obuhvaća pripremu za nastavni sat „Elektroforeza i hemodijaliza“. Nastavni sat sadrži kombinaciju frontalnog, individualnog i grupnog rada. Pomoću individualnog rada nastoji se osamostaliti učenike i naglasiti posebnost svakog pojedinca, dok se kroz grupni rad i rad u paru, potiče razumijevanje gradiva i razvoj socijalnih kompetencija učenika.
Abstract (english)
Microchip electrophoresis was created by miniaturization of capillary electrophoresis. The separation of charged species takes place in the separation microchannel under the influence of an electric field. The aim of this work is to investigate the possibility of potassium separation in children's supplements by electrophoresis on a microchip. Dietary supplements are nutritional supplements made from concentrated sources of nutrients. Due to their increasingly easy availability on the market and the increase in the number of consumers, the need for their precise analysis has risen. The presented paper examines the possibility of detecting and separating potassium in dietary supplements. A C4D detector was used for detection, and (c = 0,5 mol/dm3) acetic acid was used as the background electrolyte. With the help of linear regression analysis, a linear response was determined. The methodological part of the work includes preparation for the "Electrophoresis and Hemodialysis" lesson. The lesson contains a combination of face-to-face, individual, and group work. Individual work is used to make students independent and emphasize the uniqueness of each individual, while through group work and pair work, the understanding of the material and the development of students' social competences are encouraged.
