Abstract
Farmaceutici predstavljaju veliku opasnost ako se u okoliš ispuštaju u prevelikim i nedozvoljenim količinama. Mogu narušiti prirodnu ravnotežu, utjecati na život biljaka i životinja pa samim time i na život ljudi. Zato se u današnje vrijeme počela pridodavati veća pažnja istraživanjima koja su vezana za uklanjanje farmaceutika iz okoliša kako ne bi došlo do neželjenih posljedica. Farmaceutici su otkriveni u različitim ekološkim sredinama diljem svijeta; u otpadnim vodama postrojenja za obradu otpadnih voda, te u površinskim, podzemnim i pitkim vodama. Memantin je vrlo postojan u okolišu,teže ga je detektirati ,a isto tako i ukloniti iz okoliša. Kako bi se riješio taj problem potrebno je razviti nove tehnologije koje mogu u potpunosti ukloniti ili uništiti njegovu aktivnost. Cilj ovog istraživanja bio je procijeniti mogućnosti naprednih oksidacijskih procesa, posebno fotooksidativnih za razgradnju memantina u solar/TiO2/H2O2 procesu. U ovom eksperimentu TiO2 (titanijev dioksid) korišten je kao fotokatalizator gdje je bio imobiliziran na stakleni nosač. Ispitan je utjecaj pH i koncentracije H2O2 na brzinu razgradnje memantina, korištenjem punog faktorskog plana i metode odzivnih površina (RSM). Zamijećeno je da uklanjanju memantina pogoduje visok pH, a eksperimentalni rezultati ukazuju kako koncentracija H2O2 igra znatno manju ulogu u učinkovitosti fotokatalitičke razgradnje memantina.
Abstract (english)
The pharmaceuticals represent a great danger if they are released into the environment in excessive and unacceptable quantities. They can infringe the natural balance, affect the lives of plants and animals, and also the lives of people. So nowadays, more attention has been paid to research that is related to the removal of pharmaceuticals from the environment so as to avoid undesirable consequences. Pharmaceuticals have been discovered in various ecological environments around the world; in sewage treatment plants for wastewater treatment, and in surface, underground and drinking water. Memantine is very persistent in the environment, it is more difficult to detect it, and also remove it from the environment. To solve this problem, it is necessary to develop new technologies that can completely eliminate or destroy its activity. The aim of this study was to evaluate the possibilities of advanced oxidation processes, especially photochemical degradation of memantine in solar/TiO2/H2O2 process. In this experiment, TiO2 was used as a photocatalyst where it was immobilized on a glass carrier. The effect of pH and H2O2 concentration on memantine degradation rate was investigated, using full factor plan and RSM. It has been noted that removal of memantine favors high pH, and experimental results indicate that H2O2 concentration plays a much smaller role in the photocatalytic degradation of memantine.
