Abstract
U sklopu ovog diplomskog rada okarakterizirane su koloidne čestice anatasa te su ispitana međupovršinska svojstva titanijev(IV) oksid / vodena otopina elektrolita. Kao elektrolit je korišten natrijev klorid. Radi onečišćenja ishodnih uzoraka, prije mjerenja je provedeno čišćenje čestica. Za karakterizaciju čestica korišteno je nekoliko metoda. Potenciometrijskom masenom titracijom određena je točka nul-naboja. Potenciometrijskom kiselinsko-baznom titracijom određene su relativna površinska gustoća naboja i točka nul-naboja. Izoelektrična točka određena je metodom elektroforeze. Dobiveni podaci o izoelektričnoj točki i točki nulnaboja ukazali su na bolje vezanje natrijevih kationa na površinu čestica i zaostajanje kloridnih aniona u otopini. Veličina čestica te njihova raspodjela određene su dinamičkim i statičkim raspršenjem svjetlosti. Mjerenja su provedena na česticama različitih veličina te su rezultati međusobno uspoređeni.
Abstract (english)
For the purpose of this paper, colloidal anatas particles were described and the interfacial properties of titanium(IV) oxide / aqueous electrolyte solution were investigated. Sodium chloride was used as the electrolyte. Due to the contamination of the starting samples, particle cleaning was performed before the measurement. Several methods were used to characterize particles. Zero-charge point was determined by potentiometric mass titration. By potentiometric acid-base titration the relative surface charge density and the zero-charge point were determined. The isoelectric point was determined by electrophoresis. The obtained data on the isoelectric point and the zero-charge point indicated better binding of sodium cations to the surface of the particles and the lagging of chloride anions in the solution. Particle size and distribution were determined by dynamic and static light scattering. Measurements were performed on particles of different sizes and the results were compared with each other
