Abstract
Elektrokoagulacija (EK) je tehnologija koja je trenutno u velikom razvoju na području kondicioniranja vode i pročišćavanju otpadnih voda. Kombinirajući prednosti koagulacije, flotacije i elektrokemije omogućava mu jednostavnost uz niske operativne troškove, smanjenje taloga, mogućnost ponovne uporabe pročišćene vode i bez upotrebe dodatnih kemikalija. U okviru ovog rada ispitana je učinkovitost uklanjanja teških metala primjenom procesa elektrokoagulacije na otopini teških metala sa željeznom, aluminijskom, bakrenom i grafitnom elektrodom. Otopina je sadržavala kadmij, krom, kobalt, mangan i nikal kojima je praćena učinkovitost uklanjanja tijekom dvominutnog eksperimenta. Ispitivanje je provedeno na tri različite početne koncentracije otopine (0,1, 1, 10 ppm) kako bi se utvrdilo ima li početna koncentracija utjecaj na učinkovitost. Utvrđeno je da ima, te su pri najmanjoj koncentraciji od 0,1 ppm dobiveni najbolji rezultati učinkovitosti. Također je praćen i utjecaj materijala elektrode, gdje se bakar pokazao najučinkovitijim materijalom ali uz veliku potrošnju elektrode, dok se grafit pokazao kao neučinkovit u uklanjanju teških metala. Statistička analiza je napravljena u Stat-Ease-ovom softveru Design Expert 13, gdje je potvrđena značajnost modela i faktora.
Abstract (english)
Electrocoagulation (EC) is a technology that is currently in great development in the field of water conditioning and wastewater treatment. By combining the advantages of coagulation, flotation and electrochemistry, it enables simplicity with low operating costs, reduction of sediment, the possibility of reusing purified water and water treatment without the use of additional chemicals. In the framework of this work, the efficiency of electrocoagulation process was examined on a solution of heavy metals with iron, aluminum, copper and graphite electrodes. The solution contained cadmium, chromium, cobalt, manganese and nickel, whose removal efficiency was monitored during a two-minute experiment. The test was carried out at three different initial concentrations of the solution (0.1, 1, 10 ppm) to determine whether the initial concentration affects the efficiency. It was found that it does, and the best efficiency results were achieved at the lowest concentration of 0.1 ppm. The influence of the electrode material was also monitored, where copper proved to be the most effective material, but with a high consumption of the electrode, while graphite proved to be ineffective in removing heavy metals. Statistical analysis was done in Stat-Ease's Design Expert 13 software, where the significance of the model and factors was confirmed.
