AB  - The efficiency of iron-functionalized sepiolite for the removal of Co2+ ions from aqueous solutions was determined under different experimental conditions, using the batch method. The ionization constants of the surface functional groups of the sepiolite-iron system, determined from potentiometric titration data, were pK(a1)(int) = 6.7 +/- 0.1 and pK(a2)(int) = 10.2 +/- 0.1. The sorption experiments were performed as a function of initial metal concentration, initial pH value, and the equilibration time. The equilibrium process was well described by the Langmuir isotherm model. The pseudo-second order kinetic model provides the best correlation of the experimental kinetic data. The iron-sepiolite system had a noticeably higher Co2+ sorption capacity than the natural sepiolite sample as a result of higher specific sorption and a higher ion exchange capacity.

AB  - Titania powders were synthesized by nonhydrolitic sol-gel process starting from titanium(IV)-chloride, titanium(IV)-isopropoxide and carbon-tetrachloride. Gelation was performed in solvothermal conditions, at 140 degrees C or 160 degrees C. The obtained gels were then dried and calcined at 500 degrees C or 750 degrees C. Dry gels and powders obtained by their calcination at 500 degrees C contained only anatase, and the degree of crystallinity increased notably on passing from the dry gels to the powders. The crystallite size of dry gels and powders obtained at 500 degrees C increased slightly with increasing temperature of the gelation. The powder obtained at the higher gelation temperature had a larger specific surface area (52.8 m(2) g(-1)) and a smaller maximum pore diameter (12.3 nm). When the calcination temperature was increased to 750 degrees C, the obtained powders contained both anatase and rutile. The rutile content in the powders is related to the degree of crystallinity of the dry gels: with a lower level of dry gel crystallinity, the rutile content in the powders becomes higher, indicating that the temperature of the anatase - gt  rutile transformation decreases with decreasing the size of anatase crystallites. The photocatalytic activity of the powders obtained by gel calcination at 500 degrees C, tested by measuring the photocatalytic degradation of the azo dye CI Reactive orange 16, was sufficiently high and attained the photocatalytic activity of the broadly accepted commercial powder P-25 produced by Degussa. The photocatalytic activity of the powders obtained by calcination at 750 degrees C was low, but showed a tendency to increase with higher anatase content in the powders.

AB  - The efficiency of natural sepiolite for the removal of Cu2+ and Co2+ from aqueous solution was determined using the batch method. The sorption experiments were performed as a function of the initial metal concentration, the equilibration time and temperature. Thermodynamic parameters, such as enthalpy, free energy and entropy, were calculated from the temperature dependent sorption isotherms and these values showed that the sorption of the investigated metals onto sepiolite was endothermic. The pseudo-second order kinetic model provides the best correlation of the experimental kinetic data.

Ispitan je uticaj početnih koncentracija Cu2+ i Co2+, kao i vremena uravnotežavanja i temperature na proces sorpcije. Vrednosti termodinamičkih parametara sorpcije (promene entalpije, promene entropije, promene slobodne energije sorpcije), određene na osnovu zavisnosti sorpcionog kapaciteta od temperature, ukazuju na to da je proces sorpcije Cu2+ i Co2+ na sepiolitu endoterman. Poređenjem eksperimentalih rezultata sa kinetičkim modelima utvrđeno je da se kinetika sorpcije Cu2+ i Co2+ na sepiolitu može opisati kinetičkim modelom pseudo-drugog reda.

AB  - Inverse gas chromatography at infinite and finite surface coverages was applied to evaluate the surface properties of an iron-modified sepiolite sorbent, Fe-sepiolite. The adsorptions of different nonpolar and polar probes were measured in the infinite-dilution regime, in the temperature range 483-513 K. For the organic probes used, the thermodynamic parameters (free energy, enthalpy, and entropy) of adsorption and the dispersive and specific components of the free energy of adsorption were determined and are discussed in terms of specific reactions that can occur on the adsorbent surface. Following the approach of Gutmann (The Donor Acceptor Approach to Molecular Interactions; Plenum Press: New York, 1978), acid/base surface characteristics were determined. The adsorption isotherms of n-hexane, benzene, chloroform, and tetrahydrofuran were used to estimate the specific surface areas, isosteric heats of adsorption, and adsorption energy distributions for the adsorption of organic molecules.
