Influence of Temperature and Different Hydroxides on Properties of Activated Carbon Prepared From Saccharose. Characterization, Thermal Degradation Kinetic and Dyes Removal From Water Solutions

摘要

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.
