Abstract

Sve veća primjena pesticida i farmaceutika dovodi do povećanja njihove koncentracije u vodama. Svrstavaju se u nova onečišćivala koja imaju potencijalno toksična svojstva za ljude, al i za cijeli ekosustav. Neki od tih spojeva, nalaze se na listi prioritetnih tvari Direktive 2013/39/EU pa se njihova koncentracija u vodenom okolišu kontinuirano prati. Takva onečišćivala teško se uklanjaju konvencionalnim procesima obrade voda, pa se stoga pokušavaju razviti nove metode kojima bi se pospješilo uklanjanje. Napredni oksidacijski procesi pokazali su se kao vrlo uspješnima u uklanjanju novih onečišćivala te je interes za takve procese u porastu. Napredne oksidacijske tehnike uključuju procese temeljene na osvjetljenju UV zrakama, ozonizaciji, Fentononovim reakcijama, ultrazvuku te upotrebi ferata(VI) u procesima oksidacije. Cilj ovog istraživanja je procijeniti mogućnost oksidacije atrazina, simazina i diklofenaka feratom(VI). Ispitan je utjecaj pH i koncentracije oksidansa na konverziju navedenih onečišćivala.

Abstract (english)

The growing implementation of pesticides and pharmaceuticals results in an increased concentration of these substances in water. They are categorized as a new group of pollutants that have potential toxic characteristics harmful not only for humans, but for the entire ecosystem. Therefore, some of these substances are listed as priority pollutants within Directive 2013/39/EU, meaning that their concentration in the water environment is continuously kept under surveillance. Pollutants of this kind are difficult to eliminate by conventional water treatment processes, which is why new and hopefully more effective methods are continuously developed. Among them, advanced oxidation processes (AOPs) have proved to be highly successful; accordingly the popularity of this approach increase constantly. AOPs include processes based on UV irradiation, ozonation, Fenton reactions, ultrasound treatment and oxidation by ferrate(VI) salts. The objective of this study was to estimate the potential of oxidation of atrazine, simazine and diclofenac using ferrate(VI). The impact of pH and oxidant concentration on the conversion of the mentioned pollutants was investigated.
