High photocatalytic activity of light-driven Fe2TiO5 nanoheterostructure toward degradation of antibiotic metronidazole

Monodispersed Fe2TiO5 nanoheterostructure was prepared via simple surfactant-assisted sol-gel method using cetyltrimethylammonium bromide (CTAB). After quantitative and qualitative analysis of nanostructures, simulated light-driven performance of Fe2TiO5 thin film as heterogeneous photocatalyst toward photodegradation of antibiotic metronidazole was investigated and compared with its forming metal oxides. Results showed the highest photocatalytic activity for Fe2TiO5 after 2h of irradiation by which the pseudo first-order photodegradation reaction of metronidazole leads to water and carbon dioxide production. Increase the photocatalysis efficiency based on Fe2TiO5 photocatalyst relative to TiO2 and Fe2O3 is due to lower mean size, more uniform distribution of nanoparticles and consequently an increase in the surface area available for the photocatalytic reaction, also the two metal centers arrangement in one structure that were resulted in effective light harvesting and enhancing the probability of reduction-oxidation reactions owing to fast transferring of charge carriers to surface with promoting separation and limiting recombination.

Bio-compatible flotation of Chlorella vulgaris: Study of zeta potential and flotation efficiency

The energy-intensive dewatering of algae biomass, the first step of most downstream processes, remains one of the big challenges for economically relevant photoautotrophic bioprocesses. Due to its scalability and easy construction, froth flotation using the interactions between cells and bubbles shows considerable potential for this type of cost-efficient initial dewatering step. Comprehensive knowledge on both the physico-chemical conditions and the cellular surface properties are an important precondition to harvest cells by flotation. This study investigates the impact of changing the medium composition, specifically varying the pH and adding (bio-) collectors, on the zeta potential of Chlorella vulgaris SAG 211-1b. Decreasing the pH value from physiological to acidic conditions (pH 1-1.5) resulted in a strongly reduced cellular zeta potential. As validated by dispersed-air flotation, this yields a significantly enhanced cell recovery R > 95 %. The impact of the synthetic collector cetyltrimethylammonium bromide and the biopolymer chitosan on the cellular zeta potential and flotation performance was studied, resulting in a 3.3-fold decrease in the surfactant dose when chitosan was used . The basic mechanisms of cell-chitosan interaction were analysed in terms of particle size distribution and surface tension measurements, revealing interactions between flocculation and adsorption during the dispersed-air flotation of C.vulgarisSAG 211-1b.
