Microwave-assisted direct photolysis (MADP) of bromophenol blue (BPB) in aqueous solutions was studied using microwave (MW) powered electrodeless discharge lamps (EDLs). BPB of initial concentration 100 mg/l was efficiently degraded in the MADP process after 10 min of irradiation by EDLs. The in...

A cross-sectional analysis among 1041 urban residents was done to examine associations between self-reported walking distance to and use of freshwater urban blue space and health-related quality of life in two German cities: a city with “poor” urban blue space supply (Bielefeld; 0.8% blue spac...

Efficiently modulating the pore size, electrochemical conductivity and metal ratio of metal-organic frameworks (MOFs) is essential for improving their electrochemical catalytic activity. Herein, we develop a convenient strategy for excavating Prussian blue analogues (PBA) by using sodium sulfide...

This study deals the biodegradation of crystal violet dye by a ligninolytic enzyme producing bacterium isolated from textile wastewater that was characterized and identified as Aeromonas hydrophila based on the 16 S rRNA gene sequence analysis. The degradation of crystal violet dye was studied u...

The aggregation behavior of C.I. Basic Violet 10 in the presence of poly(sodium 4-styrenesulfonate) was modified, as a consequence of short-range interactions. In aqueous acidic media, the cationic dye forms hydrophobic ion pairs with polymeric benzene sulfonate groups which tend to aggregate in...

We prepared a W/WO3/TiO2 bicomposite photoanode by simple electrochemical anodization of W foil, followed by cathodic electrodeposition of TiO2 and annealing at 450 °C for 30 min. This photoanode shows good photoactivity under irradiation with UV and visible light. In optimized conditions, it p...

The use of hair dyes is closely associated with the increase of cancer, inflammation and other skin disorders. The recognition that human skin is not an impermeable barrier indicates that there is the possibility of human systemic exposure. The carcinogenic potential of hair dye ingredients has ...

Numerous studies have been published on water footprints (WFs) of agricultural products, but much less on WFs of industrial products. The latter are often composed of various basic materials. Already the basic materials follow from a chain of processes, each with its specific water consumption (...

Paenibacillus polymyxa is a rhizobacterium that has attracted substantial attention due to its ability to produce functional metabolites and promote plant growth. Metabolic and genetic improvements in this species will benefit research and other applications of the bacterium. However, a suitable...

Local clay mineral from Khulais area, was activated at different acid to clay mineral ratios (in mass) at 90 °C. The local clay mineral contained a major phase of smectite, in addition to kaolinite and quartz as impurities. Upon acid activation, structural changes in the treated clay minerals o...

Blue economy is a very recent concept that has emerged in the world of scientists as an alternative to the green economy that, even seems to be much more sustainable than the gray economy, is very costly. It is still a challenge to transpose the blue economy principles into practical design rule...

The presence of dyes in wastewater effluent of textile industry is well documented. In contrast, the endocrine disrupting effects of these dyes and wastewater effluent have been poorly investigated. Herein, we studied twenty-three commercial dyes, usually used in the textile industry, and extrac...

Culture filtrates from the white rot fungus Trametes trogii were used for the degradation of two azo dyes: Xylidine and Methyl Orange. These culture filtrates showed a great potential for decolorizing even high concentrations of both azo dyes, without the addition of redox mediators, possibly du...

In this research, a facile process combined chitosan adsorption and UV-Fenton advanced oxidation process (CAAOP) has been developed for the treatment and reuse of spent acid dyebaths. The acid dyes in the spent dyebaths are completely removed through the adsorption column filled with chitosan, w...

The central composite design (CCD) was applied to optimize the preparation conditions of nano-particle TiO2 photocatalysts in plasma catalysis system. The prepared TiO2 photocatalysts were used to degrade C.I. Reactive Yellow 176 (RY176) in combination with dielectric barrier discharge (DBD) pla...

Natural attenuation of polychlorinated biphenyls (PCBs) by indigenous bacteria is an effective remediation strategy for polluted marine sediments. This study investigated the relationships between PCB concentrations in sediment pore water, humin electron transfer capacity, and potential PCB dech...

Physicochemical characteristics and phytochemical profiles of red (Physalis alkekengi L., RP) and yellow (P. pubescens L., YP) Physalis fruits cultivated in three provinces of China were characterized. YP fruits showed significantly lower levels of total organic acids and elevated total sugars t...

Biomass forms a complex interwoven structure containing cellulose, hemicellulose and lignin that hinders enzymatic hydrolysis of cellulose. Enzymatic hydrolysis of the cellulose within yellow poplar (tulip tree) particles released only 9% of the total glucose in this study. To increase the acces...

Cellulose from flax shive was modified with quaternary ammonium groups to facilitate removal of C.I. Reactive Red 228 (RR228) dye from aqueous media. The adsorption of RR228 was investigated at various temperatures, adsorbent doses, initial dye concentrations and pH values. Two kinetic models we...

In this study the heterotrophic cultivation of Chlorella vulgaris NIES-227 fed with glucose was investigated systematically using six media types; combinations of nitrogen repletion/depletion and phosphorus repletion/limitation/depletion. It was found that a high yield of fatty acids (0.88 of fe...
