Abstract

Onečišćenje vode je jedan od gorućih problema s kojom se čovječanstvo danas suočava,
nažalost prvenstveno zbog neodgovornog ponašanja te nepropisnog zbrinjavanja otpada. U
vodene sustave dnevno se ispuštaju velike količine različitih otpadnih tvari kao što su
organski, anorganski i radioaktivni otpad. Različiti oblici onečišćenja vode štetno djeluju
na eko – sustav, te posljedično na ljudsko zdravlje. Zbog kontaminacije, otpadne vode
zahtijevaju dodatno pročišćavanje prije ulaska u sustave ribnjaka, potoka ili rijeka. Postoje
različiti stupnjevi i metode pročišćavanja otpadnih voda, a najefikasnija je adsorpcija. Cilj
ovog rada je usmjeren na adsorpciju octene kiseline iz vodenih otopina primjenom
otpadnih materijala kao što su troska, anodna prašina, ljuske jajeta, talog kave i aktivni
ugljen.

Abstract (english)

Water pollution is one of the burning problems that humanity is facing today,
unfortunately, mainly due to irresponsible behavior and improper waste disposal. Large
amounts of various waste materials such as organic, inorganic and radioactive waste are
released daily into water systems. Various forms of water pollution have a detrimental
effect on the ecosystem, and consequently on human health. Due to contamination,
wastewater requires additional treatment before entering the systems of ponds, streams or
rivers. There are varying degrees and methods of wastewater treatment, and the most
effective is adsorption. The aim of this paper is focused on adsorption of acetic acid from
aqueous solutions using waste materials such as slag, anode dust, egg shells, coffee
grounds and activated coal.
