Abstract: The adsorption of Acid Brilliant Blue on biogas residual slurry has been investigated. The parameters studied include dye concentration, agitation time, adsorbent dosage and pH. The equilibrium data fit well with both the Langmuir and Freundlich models of adsorption isotherm. Maximum removal of 99% was observed at pH 2.56. Desorption studies indicate that the dye is solubilised in 50%(v/v) acetic acid to the extent of 59% and the remainder appears to be chemically complexed irreversibly to the adsorbent.

Abstract: A receptor modeling approach has been applied to identify and apportion sources of airborne particulate matter in Thessaloniki, Greece, The absolute principal component analysis source apportionment technique used, provided quantitative information regarding both source particle characteristics and impacts. The analysis identified four major sources of heavy metals within total suspended particles (TSP) in the centre of the city: oil burning, pyrometallurgical non-ferrous metal processes, motor vehicles and soil resuspension. Their contributions to TSP estimated by regression on absolute principal component scores (APCS) were 12%, 8%, 5% and 4%, respectively. A similar analysis conducted for a sampling site close to the industrial area identified five major sources: oil burning, industrial Cr source, soil resuspension, pyrometallurgical non-ferrous metal processes and motor vehicles with contributions 20%, 15%, 9%, 8% and 4%, respectively.

Abstract: Two different receptor models were applied for the source apportionment of airborne particulate matter in Thessaloniki, Greece. The two models, regression on absolute principal component scores and a modified version of factor analysis/multiple regression, were developed using heavy metal concentration data within total suspended particles. The results indicate that the use of more than one receptor modeling approach is a useful validation tool when apportioning sources of the suspended particulate matter. The type of sources resolved by both approaches were similar. Source contribution estimates and source emission profiles calculated with the two modeling approaches were also comparable.

Abstract: Four adsorbents have been prepared from industrial wastes obtained from steel and fertilizer industries and investigated for their utility to remove anionic dyes. Studies have shown that the adsorbents prepared from blast furnace sludge, dust and slag have poor porosity and low surface area resulting in very low efficiency for the adsorption of dyes. On the other hand, carbonaceous adsorbent prepared from carbon slurry waste obtained from fertilizer industry was found to show good porosity and appreciable surface area and consequently adsorbs dyes to an appreciable extent. The adsorption of two anionic dyes viz. methyl orange and brilliant blue G on carbonaceous adsorbent conforms to Langmuir equation, is a first order process and pore diffusion controlled. As the adsorption of dyes investigated was appreciable on carbonaceous adsorbent, its efficiency was evaluated by comparing the results with those obtained on a standard activated charcoal sample. It was found that prepared carbonaceous adsorbent exhibits dye removal efficiency which is about 90% of that observed with standard activated charcoal sample. Thus, it can be fruitfully used for the removal of dyes and is a suitable alternative of standard activated charcoal in view of its cheaper cost.

Abstract: In this study, removal of arsenazo(III) using activated carbon (AC) and multiwalled carbon nanotubes and of methyl red using AC from waste water is reported. The influences of pH, temperature, concentration of the dye, amount of adsorbents, particle size of adsorbent, and contact time on the efficiency of removal from aqueous solution are investigated. Adsorption experiments indicate that the extent of adsorption is strongly dependent on the pH of the solution. Changes in free energy of adsorption (ΔG(0)), enthalpy (ΔH-0), and entropy (ΔS-0) are calculated to understand the nature of adsorption. The calculated values of ΔG(0) indicate that the adsorption process is spontaneous. The estimated values of ΔH-0 and ΔS-0 are positive which indicates that the adsorption process is endothermic and that the dye molecules are organized on the adsorbent surface in a more random fashion than in solution. The dye adsorption process follows a pseudo-second-order model under involvement of an intra-particle diffusion mechanism. Standard adsorption isotherms are used to fit the experimental data.

Abstract: Nano-structured rod-shaped particles of 6-line ferrihydrite were synthesized at ambient temperature under controlled conditions. The phase formation was confirmed through X-ray diffraction (XRD). Shape and size of the particles were observed by transmission electron microscopy. Batch sorption studies for Pb(II), Cd(II), and Cu(II) were carried out. A pseudo second order rate model fitted to the kinetic data was obtained for the three cations. By increasing the pH from 2.0 to 5.3, sorption of the three cations increased. At a pH of 5.3, maximum loading capacities were 0.4, 0.7, and 0.9 mmol g^-1. The isothermal data for Pb(II) and Cu(II) fitted to the Langmuir model, the Cd(II) data to a Freundlich isotherm. Cu(II) uptake increased with an increase of Cl^- concentration, that of Cd(II) decreased. The Pb(II) uptake capacity passed through a maxima of 25 mg L^-1 Cl^-. Presence of [image omitted] had beneficial effect on the sorption of both Cu(II) and Pb(II) but affected Cd(II) sorption adversely. Depending on the sorbed metal ion, XRD results showed disappearance, shift in d-values, or variation in relative intensities. The sorption from solutions containing two or all three of the metal ions exhibited some selectivity.
