One pollutant which seriously threatens water resources is dye. Therefore, finding a suitable method to separate the dye in water resources is very important. An adsorption process that uses low cost adsorbents is considered as an efficient strategy for this purpose. In this study, Erythrosine dye removal from an aquatic environment using natural absorbents, namely Sorghum and Ziziphus nummular...

natural dye extract of walnut shell, was extracted using an ultrasonic processor and purified by hot saponification method, has been studied as a novel sensitizing dye to fabricate tio2 nanoparticles based dye sensitized solar cells (dssc). the extract was characterized using uv–vis absorption spectroscopy and fourier transform infrared (ftir) employed to identify the anchoring groups in walnut...

introduction: colored compounds which often are toxic and carcinogen is one of the environmental pollutants. these pollutants should be removed prior than discharge to the environment. the aim of this study was the evaluation of maize tassel powder efficiency for the removal of reactive red 198 dye from synthetic textile wastewater. materials & methods: this experimental study was performed in ...

Ten phenols were selected as natural laccase mediators after screening 44 different compounds with a recalcitrant dye (Reactive Black 5) as a substrate. Their performances were evaluated at different mediator/dye ratios and incubation times (up to 6 h) by the use of Pycnoporus cinnabarinus and Trametes villosa laccases and were compared with those of eight known synthetic mediators (including -...

This study presents the natural dye recovery from various biodegradable temple and household wastes. The raw material for colour extraction consisted residual flowers and garlands from various temples as well as onion and vegetables peels from vegetable markets, university hostels, and households, which were washed, dried, crushed, and sieved. The extracted natural colours were produced by mean...

Dye-sensitized solar cell (DSSC) provides high ability of renewable energy generation. One the main factors affects performance DSSC is type dye applied as a sensitizer. Natural sensitizers have become major concern due to widely availability in world and environmentally friendly characteristic. However, need improve natural dyes based very important. This review was conducted present recent st...
