Abstract
Ovim istraživanjem je prikazana mehanokemijska sinteza kalcijeva oksalata, bez i uz prisutnost otapala (vode), u planetarnom kugličnom mlinu. Sva istraživanja do sada su ponajviše bila usmjerena na sintezu kalcijeva oksalata otopinskom kemijom. Ovim radom nastojalo se opisati drugačiji pristup, kako bi se pridonijelo novim saznanjima o sintezi kalcijeva oksalata, ekološki osvještenijom, mehanokemijskom metodom. Konačni cilj istraživanja jest sinteza, karakterizacija te identifikacija pojedine hidratne faze, dobivene reakcijom kalcijeva nitrata tetrahidrata i natrijeva oksalata. Reakcija je praćena u ovisnosti o vremenu reakcije i brzini mljevenja. Strukturna i termička svojstva uzoraka ispitana su FT-IR spektroskopijom i termogravimetrijskom analizom (TGA). Morfološke osobine kalcijeva oksalata, kao i klasifikacija veličine čestica, određene su optičkom mikroskopijom i metodom dinamičkog raspršenja svjetlosti (DLS).
Abstract (english)
The study presents the mechanochemical synthesis of calcium oxalate, without and in the presence of solvents, in a planetary ball mill. All studies so far have focused mainly on the synthesis of calcium oxalate using solution chemistry. In this paper, we described a different approach that could contribute to new findings in the field of calcium oxalate synthesis using mechanochemical approach. The ultimate goal of the research is synthesis, as well as structural characterization and identification of individual oxalate hydrate phase, gained by the synthesis of calcium salts (of the chlorides, nitrates and sulphates). The reaction is monitored depending on the duration of the synthesis, to determine if the effect of the milling velocity on the reaction exists. Structural and thermal properties of the sample were tested by FTIR spectroscopy and thermogravimetric analysis (TGA). Morphological properties of calcium oxalate as well as particle size distribution are gained by optical microscopy and dynamic light scattering (DLS).
