AB  - In presented paper, influence of temperature, precursor concentration and different hydroxides on properties of activated carbon obtained from saccharose were investigated. The samples were prepared by hydrothermal treatment and activated using KOH, NaOH and DOH. Two saccharose concentrations (0.5, 1.0 mol/dm(3)) and three temperatures (160, 200, 240 degrees C) were changed in hydrothermal treatment. Activation processes were performed at 750 degrees C under N-2 atmosphere. Samples were characterized by X-ray powder diffractometry, elemental analysis, N-2 adsorption-desorption measurements, Fourier-transform infrared spectrometry, scanning electron microscopy and thermal analysis. The obtained samples were tested for potential application in dyes removal from water solutions.

AB  - Activated carbons (ACs) were successfully prepared using plane tree seed (PTS) as a cheap and renewable raw material. The plane tree seeds were firstly treated combining magnetic (MM) and ultrasonic mixing (USM) during 0.5, 1 and 3 h in 1 M, 3 M and 6 M of H3PO4 solutions, and then activated at 260 degrees C during 20 h (low temperature hydrothermal carbonization-low HTC) in above mentioned solutions of the same molarity. The influence of combined mixing and activation processes on physical, structural and morphological properties, and their optimization was studied by X-ray powder diffraction (XRPD), Raman spectroscopy, nitrogen adsorption-desorption isotherms, fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) analysis.

AB  - A carbon-rich solid product has been synthesized by hydrothermal treatment from fructose with HNO3 at temperature of 140°C. The concentration of the precursor was changed in order to investigate how its change influences formation of carbon microspheres. pH value for every sample was the same, i.e. 1. The formation of the carbon rich solid through the hydrothermal carbonization of fructose is the consequence of dehydration reactions. Obtained carbon material is made of spherical micrometer-sized particles with the diameter in the 1-6 µm range, which can be modulated by modifying the concentration of fructose in solution. The best results are obtained with smaller concentrations of fructose. Spherical particles have more regular shape and they are less agglomerated. The structure and surface chemical properties of obtained material were characterized by scanning electron microscopy (SEM), Fourier-transform infrared (FTIR) spectra and elemental analysis.
AB  - Čvrsti proizvod bogat ugljenikom je sintetizovan hidrotermičkim tretmanom fruktoze sa HNO3 na temperaturi od 140 °C. Koncentracija prekursora bila je menjana da bi se istražilo kako njegova promena utiče na formiranje mikrosfere atoma. pH vrednost za svaki uzorak bila je isti 1. Formiranje čvrstog proizvoda bogatog ugljenikom preko hidrotermičke karbonizacije fruktoze posledica je dehidracionih reakcija. Dobijeni ugljeni materijal izrađen je od sfernih čestica veličine prečnika od 1 do 6 µm, koji se može modulisati promenom koncentracije fruktoze u rastvoru. Najbolji rezultati se dobijaju sa manjim koncentracijama fruktoze. Sferne čestice imaju više pravilan oblik i oni su manje aglomerisane. Strukture i površinske hemijske osobine dobijenog materijala su sagledavane skeniranjem elektronskim mikroskopom (SEM) , FTIR-om i spektralnim i elementarnim analizama.
