Abstract
Iako korozija konstrukcijskih materijala predstavlja negativnu pojavu, kada se elektrokemijski postupci koriste za pročišćavanje otpadnih voda, anodno otapanje metala može imati pozitivan učinak. U ovom radu, ispitan je utjecaj različitih gustoća struje nakon primjene u obradi otpadne vode hibridnim procesom elektrokoagulacije i sintetskog zeolita. Ispitan je i utjecaj različitih veličina čestica zeolita na otapanje elektrode, stanje površine elektrode i efikasnost uklanjanja. Površina elektroda analizirana je snimanjem sa svjetlosnim mikroskopom uz različita uvećanja. Ispitan je utrošak aluminijevih elektroda tijekom hibridnog procesa elektrokoagulacije u prisustvu sintetskog zeolita, te su izvedeni zaključci o stanju površine elektroda nakon odvijanja hibridnog procesa. Bolja efikasnost uklanjanja dobivena je provođenjem eksperimenta pri većim gustoćama struje kao i kod sustava koji su se provodili uz dodatak zeolita veće veličine čestica. Značajno veća oštećenja su na elektrodama koje su se koristile u eksperimentu s dvostruko većom gustoćom struje. Također, značajna oštećenja su zamijećena na elektrodi koja su se koristila u eksperimentu s većim česticama zeolita, što se može povezati s njihovim izraženijim abrazivnim djelovanjem.
Abstract (english)
Although the corrosion of structural materials is a negative phenomenon, when electrochemical processes are used for wastewater treatment, anodic dissolution of metals can have a positive effect. In this work, the influence of different current densities was investigated after they were used in wastewater treatment by a hybrid process of electrocoagulation combined with the addition of synthetic zeolite. Also, the influence of different zeolite particle size on electrode dissolution, electrode surface condition and removal efficiency were tested. The surface of the electrodes was analyzed by recording it with a light microscope at different magnifications. The consumption of aluminum electrodes during the hybrid process of electrocoagulation in the presence of synthetic zeolite was examined, and conclusions were drawn about the condition of the surface of the electrodes after the hybrid process. Better removal efficiency was obtained by conducting the experiment at higher current densities and in systems using larger zeolites particles. The electrodes used in the experiment with double current density were significantly more damaged. Significant damage was also observed on the electrode used in the experiment with larger zeolite particles, which can be associated with the stronger abrasive effect.
