Abstract

Opstanak svijeta i živih bića ovisi o vodi pa nedostatak vodenih resursa dovodi do ozbiljnih problema. Više od 50 % svjetske populacije se suočava s nestašicom vode. Neki od uzroka tome su konstantan rast stanovništva, onečišćenje površinskih i podzemnih voda, neodgovarajuća raspodjela vodenih resursa te povremene suše. Onečišćena voda jednako utječe i na životinjski i biljni svijet. Smrt mnogih vodenih životinja posljedica je ulaska onečišćene vode u more. Budući da naš svijet nije odvojen od svijeta vodenih bića, ptica i biljaka, opasnost od ovih uzastopnih onečišćenja sve je veća i veća. U današnje vrijeme porast emisija industrijskih otpadnih voda predstavlja sve veći problem. Među opasnijim onečišćivalima ističu se fenolni spojevi čije je određivanje ključno za procjenu kvalitete vode i za sigurnost okoliša. Oni predstavljaju značajan rizik za ekosustav i ljudsko zdravlje zbog svojih toksičnih i kancerogenih svojstava. Ovaj rad ima za cilj istaknuti analitičke metode određivanja fenola u otpadnim vodama. Od analitičkih metoda, ističu se spektrofotometrijska metoda, tekućinska kromatografija visoke učinkovitosti (engl. High-Perfomance Liquid Chromatography, HPLC) i masena spektrometrija (engl. Mass Spectrometry, MS). Odabir odgovarajuće metode ovisi o sastavu i količini vode koja se obrađuje, željenoj učinkovitosti postupka, ekološkoj prihvatljivosti te operativnim troškovima.

Abstract (english)

The survival of the world and of living beings depends on water. Therefore, the deficiency of water resources can cause serious problems. More than 50 % of the world's population faces some form of water deficiency. Some of the causes are the constant population growth, the pollution of both surface and ground waters, the inadequate distribution of water resources and the occasional droughts. Moreover, polluted water equally affects the animal and the plant kingdoms and the death of many water animals is a direct consequence of polluted water entering the sea. Given the fact that our world is not separated from the worlds of animals, birds and plants, the danger of these various types of pollution becomes greater every day. Today, the increasing emission of industrial wastewater represents a growing issue. Phenolic compunds can be traced among the most dangerous pollutans and their identification is crucial for the water's quality assessment and for the environment's safeguard. They represent a high risk for the ecosystem and for the human health due to their toxic and carcinogenic properties. This thesis gives an overview of analytical methods for the detection of phenols in wastewater. Among the analytical methods, spectrophotometric method, High Performance Liquid Chromatography and Mass Spectrometry need to be pointed out. The choice of an appropriate method depends on the composition and quantity of water, the desired efficiency of the process, environmental acceptability and operational costs.
