AB  - The release of industrial wastewater into the ecosystem prompted our research on the development of an efficient and biodegradable material that can be used for wastewater treatment. We optimized preparation of porous material from poly(lactic acid) (PLA) by variation in solvents and drying methods (air-drying vs. supercritical CO2-drying). In addition, we optimized the method of TiO2 nanoparticles immobilization (in situ vs. ex situ) onto porous PLA. The material properties and functionality were verified by SEM, water displacement, gas adsorption-desorption, Hg-intrusion porosimetry, dye degradation, FTIR, TGA/DSC, and water contact angle analysis. We showed that the morphology of PLA material could be controlled by variation in process parameters resulting in porosity from 43% to 73%. The prepared material sustained floatability for longer than 4 weeks and provided complete discoloration of dye C.I. Acid Orange 7 after 240 min of illumination. The high photocatalytic activity was preserved within three repeated cycles.

AB  - This study discusses the possibility of using corona pre-treated polypropylene (PP) non-woven fabric as a support for immobilization of colloidal TiO2 and Ag nanoparticles in order to remove dye C.I. Acid Orange 7 from aqueous solution. Dye removal efficiency by sonocatalysis, photocatalysis and sonophotocatalysis was evaluated on corona pre-treated fabric loaded with TiO2 nanoparticles, corona pre-treated fabric double loaded with TiO2 nanoparticles and corona pre-treated fabrics loaded with TiO2 nanoparticles before and after deposition of Ag nanoparticles. In addition, the stability of PP non-woven fabric during these processes was investigated. The substrates were characterized by SEM, EDX and AAS analyses. The change of the dye concentration was evaluated by UV-VIS spectrophotometry. Unlike sonocatalysis and photocatalysis, complete dye removal from both solution and non-woven fabric was obtained already after 240-270 min of sonophotocatalysis. Corona pre-treated PP non-woven fabric loaded with Ag nanoparticles prior to deposition of TiO2 nanoparticles provided excellent degradation efficiency and superior reusability. Sonophotocatalytic degradation of dye in the presence of all investigated samples was the most prominent in acidic conditions. Although this nanocomposite system ensured fast discoloration of dye solution, TOC values of water measured after sonophotocatalysis were not satisfactory because of PP degradation. Therefore, it is suggested to include TOC evaluation in each case study where different supports for TiO2 nanoparticles are used since these nanoparticles may guarantee the dye removal from solution but the stability of support could be problematic causing even more serious environmental impact.

AB  - Macroporous poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate)with attached diethylene triamine [PGME-deta] with high amino-groupcontent was used for the investigation of the Pd(II) sorption kinetics frommixed chloride/nitrate aqueous solutions in acidic medium (pH 2.0) atT=298 K. Four kinetic models were employed in order to comprehend themechanism of Pd(II) sorption. The maximum experimental Pd(II) sorptioncapacity at initial pH 2.0 and 298 K was 20 mg g-1.
