Activated Carbon for Wastewater Treatment from Phenol Compounds

Külümkan SARTOVA | Emil ÖMÜRZAK

Application of activated carbon (AC) obtained from cotton wastes (bolls, stems, and roots) for phenol adsorp-tion from water, or wastewater dephenolization, is presented. The kinetics of phenol adsorption by carbon adsor-bents were studied using UV/Vis spectrophotometer. The porosity of the formed ACs ranged from 1.952 to 2.339 cm3/g, the volume of macropores was from 1.79 to 2.09 cm3/g, while the commercial sample BAU-A showed 1.920 and 1.320 cm3/g, respectively. The highest phenol adsorption rate, 32.49-52.80 mg/(g center dot min), was observed for contact time up to 5 min on carbon adsorben ...Более

Activated carbon obtained from the cotton processing wastes

Külümkan SARTOVA | Emil ÖMÜRZAK | Bakıt BORKOYEV

Activated carbon (AC) was obtained from the cotton (Gossypium malvaceae) processing waste materials. The process was carried out by carbonization at 500–800 °C and subsequent activation at 800 °C by water stream. Cotton biomass is a renewable, low-cost alternative source for textile and food products; however, it hasn't been used for manufacturing of an activated carbon by carbonization in a boiling layer method. Characterization of adsorbents by means of Scanning Electronic Microscope and FT-IR showed that high porosity of carbonized products which was achieved and functional groups were form ...Более

Thermal and Optical Properties of In and In2O3 Nanoparticles Synthesized Using Pulsed Plasma in Water

Emil ÖMÜRZAK

We present small indium (In) nanoparticles with an average diameter of 4.5 nm synthesized by pulsed plasma in water. Slightly increased lattice constants and thermal stability of the tetragonal In are revealed by X‐ray diffraction analysis, Rietveld refinement, and thermogravimetric analysis. The highly crystalline body‐centered cubic indium oxide (In2O3) nanoparticles with an average diameter of 12 nm and various shapes (semispherical, semihexagonal, and semicubic) are obtained by annealing the as‐synthesized In nanoparticles at 450 °C. The bandgap energy of the In2O3 nanoparticles is 3.63 eV ...Более
