Abstract
Cilj ovog rada je bio ukloniti ione iz vodene otopine NaCl metodom kapacitivne deionizacije pri čemu je korišten elektrokemijski protočni reaktor. Prilikom odabira materijala za izradu elektroda ispitana su svojstva grafitne elektrode i grafitne elektrode s premazom od aktivnog ugljika. Ispitivanje je provedeno metodom cikličke voltametrije pri čemu je korišten dvoelektrodni ili troelektrodnom sustav. U slučaju kad je tijekom polarizacije korištena grafitna elektroda s premazom aktivnog ugljika dobivene su 10 puta veće vrijednosti struje u odnosu na slučaj kad je korištena elektroda od grafita. Stoga su prilikom izvedbe reaktora korištene elektrode s premazom od aktivnog ugljika.. Proces kapacitivne deionizacije je proveden pri konstantnom naponu od 1 V pri brzinom protoka od oko 9 ml s^-1. Tijekom provedbe procesa mjerio se pad električne provodnosti u otopini NaCl i promjena struje kroz 2 sata. Iz promjene električne provodnosti došlo se do zaključka da je uklonjen mali udio iona iz otopine. Praćenjem vrijednosti struje u vremenu bilo je moguće izračunati potrošnju energije koja u ovom procesu iznosi 55 Wh m^-3.
Abstract (english)
The goal of this work was to use capacitive deionization process in order to remove ions from NaCl solution. For this purpose flow through electrochemical reactor was used. The properties of graphite electrodes and graphite electrodes coated with activated carbon were studied by mean of cyclic voltammetry. The measurements were carried out by using two-electrode or three-electrode systems. By using graphite electrodes coated with activated carbon ten times higher currents were registered than current registered for graphite electrode. For this reason graphite electrodes coated with activated carbon were selected to be used in electrochemical reactor. The capacitive deionisation process was carried out at a constant voltage of 1 V at a flow rate of about 9 ml s^-1. The ionic conductivity of the NaCl solution and the current values were monitored during two hours. From the value of the ionic conductivity decrease it was concluded that a low degree of ions was removed from the solution. The current value enabled calculation of the energy consumption that was obtained to be 55 Wh m^-3.
