Nanometric size (Ba, Yb) doped ceria powders with fluorite-type structure were obtained by applying selfpropagating room temperature methods. Tailored composition was: Ce0.95-xBa0.05YbxO2-? fixed amount of Ba - 0.05 and varying Yb content 'x' from to 0.2. Powder properties such as crystallite particle lattice parameters have been studied. R?ntgen diffraction analyses (XRD) used characterize the samples at temperature. Also, high treatment (up 1550?C) was follow stability solid solutions. The...
A novel method for synthesis of carbon cryogel/zeolite composites was obtained. Method considers forming cryogel from the sol-gel polycondenzation resorcinol and formaldehyde, followed by freeze drying, subsequent pyrolysis in presence different amount zeolite. Characterization composite materials nitrogen adsorption shows that samples are micro- mesoporous specific surface area decrease with increasing zeolite samples. XRD confirms amorphous structure crystalline zeolite, i.e. has not been...
In this work, the reliability of image analysis for numerical evaluation Basic Red 46 (BR 46) dye adsorption process was studied. The carried out on adsorbed onto SBA‐15 mesoporous silica, by use Image‐Pro Plus software. Pixel‐specific calibration curves were derived and used to obtain concentration from three different primary color channels (red, green, blue) recorded at each pixel. order establish credibility method quantification processes, these data compared with parameters obtained...
Influence of iron on the crystallization mechanism mullite obtained from hybrid gels and doped with different concentrations was examined. DTA analysis showed that addition had a beneficial effect formation leading to temperature decreasing as amount increased. X-ray diffraction M?ssbauer spectroscopy confirmed increased content in lattice, which led an increase unit parameter related higher regular octahedra, disordered tetrahedra oxygen vacancies. Plate-like morphology observed by SEM...
This study focuses on Pb2+ and As(V) adsorption mineral heterostructures based a mixture of Si, Fe, Ti oxides (MOHs). Various techniques were performed to analyze the morphological structural properties synthesized metal oxide samples. In addition experimental optimization parameters determined by response surface method (RSM), effects pH, adsorbent dosage, temperature, contact duration batch column system efficiency single-component simultaneous lead arsenate removal tested. The...
In this study, clay from the Kolubara mine in Serbia was used to make filters as a separation media. This consequence, explores scientific area of developing porous materials natural minerals and areas environmental protection. After purification, H3BO3 contents 2 wt.% 0.5 were low-cost, environmentally friendly chemical create structure. The influence different amounts on ability filter monitored. Additionally, various synthesis conditions, such low pressing pressure up 60 MPa sintering...
In present study FeAl-LDH@SiO2 adsorbent was used for phosphate and arsenate removal from aqueous solutions. Silica, obtained rice husks, as a substrate the deposition of FeAl based layered double hydroxides (FeAl-LDH) particles. Synthesis FeAl-LDH, at Fe/Al molar ratio 3:1, performed via co-precipitation concomitant on SiO2 carrier 1:1, 2:1, 3:1 LDH/silica mass ratios. The prepared materials were characterized by scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), N2...
Amorphous iron (III) oxide was obtained from clay, using ammonium hydroxide as a precipitating agent. Influence of freeze drying under vacuum, method, on particle size, chemical composition, and crystallinity powder investigated. After drying, precipitate annealed in air at 500?C 900?C. X-ray diffraction, size analysis, scanning electron microscopy, energy dispersive spectrometry, Fourier transform infrared spectroscopy, thermogravimetric differential thermal analysis were used to...
Diatomite (diatomaceous earth) and clay minerals deposits from the mining basin Kolubara, Serbia, are natural materials with high economic potential in many fields. As received treated materials, diatomite were characterized using X-ray diffraction, mercury intrusion porosimetry, particle size distribution, scanning electron microscopy, Fourier-transform infrared spectroscopy. Activity concentrations for radionuclides 40K, 226Ra 232Th anthropogenic radionuclide 137Cs determined by gamma...
Investigated the possibility of using methyl methacrylate (MMA) as an acrylic binder in preparation ceramic powder alumina for pressing with intention improving machinability flakes. Compared properties green bodies and their corresponding sintered samples that are prepared without binder. The achieved higher density MMA (2.35 g/cm3) compared to (2.11 were formed under optimal pressure 60 MPa, indicating improved packing addition acrylate. In case samples, porosities increased, percentage...
