Resumo | Carbon fibers (CF) are lightweight materials and are associated to excellent mechanical properties, high thermal and electrical conductivity and low thermal expansion coefficient. These characteristics have been attracted attention of many research groups in different science field and application [1-5]. One of the most applications used for CF is the activating. The activated carbon fibers (ACF) have an interesting adsorption capacity. The adsorption capacity is due to the ACF have well-defined pore structures which provide a high specific surface area in contrast with CF. ACF is one of the most widely used adsorbent materials around the world. Normally, ACF is used for the drinking and waste water treatment and in many other applications where the removal of generally dispersed contaminant molecules is desired [6]. The goal of this work was to produce inexpensive activated carbon fibers and characterization the fibers for future applications in metallic substance removal from water. In this work, the carbon fibers were produced from the carbonization of Brazilian textile polyacrylonitrile fiber. Carbon fiber were produced from PAN fiber oxidation in air (260°C) and carbonized in argon atmosphere at 900°C. The activation process was performed immediately after carbonization by shifting the argon gas to CO2 and rising up the temperature to 1000°C during 50 min. The morphologies of activated and not activated carbon fiber were characterized by scanning electron microscope (SEM). The morphological surface analyze indicated the existence of pore on the surface of the ACF increasing the surface roughness and wetting ability. X-ray photoelectron spectroscopy (XPS) was used to measure presence of oxygen content on the fibers. It was observed by XPS a high intensity in the capture of the carbon electrons of the ACF this shown a significant reduction of oxygen in the ACF. Raman spectroscopy and X-ray diffractometer (XRD) were used to structural characterization. By using the Raman spectroscopy was possible to analyze fibers superficially while XRD analyzed more internal structures. The Raman spectrums were fitted in four Gaussian and one Lorentzian curve as reported in literature. The Raman results showed that the ACF presented an increase on D peak, which is linked to the disorganization of the graphitic structure. According to the DRX the CF had higher crystallites that the ACF, this decrease in crystallite was due to the surface tension during the activation process. These results are in according to the SEM and XPS results giving additional information about the influence of the activating for adsorption property of the ACF. |
