Abstract:V diplomskem delu je bil izveden proces adsorpcije in desorpcije različnih komponent: (benzojske kisline, oleinske kisline, estra oleinske kisline in kvercetina) na različne nosilce. Uporabili smo naslednje nosilce: silikagel, neusilin, aerogel hidrofilen SiO2, aerogel hidrofoben MTMS 07, Amberlite IRA 420, Amberlite XAD 16. Proces adsorpcije in desorpcije je bil izveden s klasično kolonsko kromatografijo. Adsorpcijo in desorpcijo smo izvajali pri sobni temperaturi in pretoku 1 ml/min. Maso adsorbirane in desorbirane komponente smo določili z gravimetrično metodo. Z raziskovanjem smo ugotovili, da se komponente različno vežejo na adsorbent. Masa adsorbirane in desorbirane komponente je odvisna od izbire komponente, topila, časa ter pretoka. Dokazali smo, da ima vsaka komponenta različne lastnosti glede na nosilec. Za benzojsko kislino smo dokazali, da je za adsorpcijo najprimernejši izmenjevalec amberlit IRA 420, za desorpcijo pa amberlit XAD 16. Za oleinsko kislino smo dokazali, da je prav tako za adsorpcijo najprimernejši ionski izmenjevalec Amberlite IRA 420, za desorpcijo pa Amberlite XAD 16. Za ester oleinske kisline smo dokazali, da je za adsorpcijo najprimernejši ionski izmenjevalec silikagel, za desorpcijo pa Amberlite IRA 420. Za kvercetin smo dokazali, da je za adsorpcijo najprimernejši izmenjevalec Amberlite IRA 420, za desorpcijo pa silikagel. Dokazali smo tudi, da bi za kvercetin morali izboljšati tehniko izvedbe adsorpcije, pri desorpciji pa izbrati druga topila.

Title:ADSORPTION AND DESORPTION OF CERTAIN NATURAL COMPOUNDS ON VARIOUS ADSORBENT
Abstract:The (diploma) thesis presents the process of adsorption and desorption of different components: (benzoic acid, oleic acid, oleic acid ester and quercetin) with different carriers. For our research we used the following carriers: silicagel, neusilin, hydrophilic aerogel SiO2, hydrophobic aerogel MTMS 07, amberlite IRA 420, amberlite XAD 16. The process of adsorption and desorption was performed with the classic column chromatography method at room temperature and a flow rate of 1ml/min. The resulting mixture was then poured into a column and we began with the adsorbtion. The mass of the adsorbate and desorbate component was determined with the gravimetric method. Through our research we discovered, that the components each bind differently to the adsorbent. The mass of the adsorbate and desorbate component is dependent upon the choice of components and solvents, time and flow rate.
Keywords:adsorption, desorption, benzoic acid, oleic acid, oleic acid ester, quercetin
