Abstract
Cilj ovog rada bio je ispitati fotoelektrokemijska svojstva BiVO4 i BiVO4/rGO elektroda elektrokemijskim metodama karakterizacije, te odrediti djelotvornost fotoelektrokemijskog (PEC) elektrokemijskog (EC) i fotokatalitičkog (PC) procesa. Ispitivanja su provedena u otopinama 5-aminosalicilne kiseline i fenola masenih koncentracija 28 mg/L, salicilne kiseline masenih koncentracija 28 mg/L i 14 mg/L, te 0,1 M otopini NaCl. Cilj je bio utvrditi koja aromatska tvar pokazuje najveći stupanj razgradnje te odrediti kako pH, napona i koncentraciju utječu na brzinu razgradnje. Primjenom kronoamperometrije i linearne voltametrije pokazano je da se uz BiVO4/rGO elektrodu postiže veća djelotvornost razgradnje u odnosu na BiVO4 elektrodu. Utvrđeno je da najvjerojatnije dolazi i do ireverzibilnih promjena u rGO strukturi tijekom izvedbe PEC procesa. Metodom tekućinske kromatografije visoke djelotvornosti (HPLC) praćena je koncentracija tijekom razgradnje iz čega su određeni optimalni pH uvjeti za razgradnju pojedine aromatske molekule korištene u ovom radu. Osim toga utvrđeno je kako napon i koncentracija utječu na proces razgradnje.
Abstract (english)
The main goal of this study was to investigate photoelectrochemical properties of BiVO4 and BiVO4/rGO electrodes by electrochemical methods of characterization, as well as, to determine efficiency of photoelectrochemical (PEC), electrochemical (EC) and photocatalytic process (PC). Electrodes were tested in 0,1 M aqueous solution of NaCl before and after PEC process. Degradation of salicylic acid, 5-aminosalicylic acid and phenol was carried out. The selected compounds were tested in order to find out which aromatic compound is most susceptible to degradation under certain conditions of pH, voltage and concetration. Chronoamperometry and linear sweep voltametry have shown that higher degradation efficacy is achieved by using BiVO4/rGO electrode compared to BiVO4 electrode. Results also indicate that irreversible changes of rGO structure take place during PEC procces. The decrease in concetration value during degradation process was monitored by high preformance liquid chromatography (HPLC). The obtain results indicate the optimal pH value for degradation of each aromatic compound used in this study. In addition, the influence of voltage and concentration on degradation proces was found.
