Sažetak
The effects of guanylurea phosphate on the properties of precipitates formed by forced hydrolysis of FeCl3 solutions were investigated using a combination of XRD, 57Fe Mössbauer, FT-IR and FE SEM analyses. Samples were prepared at 160 °C by varying the concentration of FeCl3 solutions and the amount of guanylurea phosphate added. This study showed that this simple method can be used to prepare giniite (Fe5(PO4)4(OH)3‧2 H2O) as a single phase with a variety of particle shapes. Three main phases, giniite, akaganeite (β-FeOOH) and hematite (α-Fe2O3), were obtained, where the exact phase composition of precipitates depended on the chemical conditions in the starting solutions. The optimum conditions for the formation of different dendritic nano/microstructures were 2‧10−3 and 5‧10−3 M FeCl3 solutions containing guanylurea phosphate. This proposed method of giniite synthesis has potential in the further investigation of the formation nature of dendritic nano/microstructures.
