Untreated wastewater disposal containing synthetic dyes produces serious problems in the environment. Industrial wastewater containing dye requires treatment by a suitable process before discharging into the environment. The present study has been performed as a batch experimental study. Nanochitosan was synthesized from the Persian Gulf shrimp shell. The effect of the various parameters in...

This study was aimed to investigate the amount of reactive blue 29 (RB29) dye removal from aqueous solution by Chitosan extracted from Persian Gulf shrimp shell. The effect of parameters such as pH, the concentration of reactive blue 29 dye, contact time, and adsorbent dosage in dye removal was studied. Isotherm, Thermodynamics, and kinetics of adsorption process were also investigated. The...

The majority of anthraquinone dye released to the environment come from antrapogenic sources. Several techniques are available for dyes' removal. In this study removal of reactive blue 29 (RB29) by an advanced oxidation process sequenced with single wall carbon nanotubes was investigated. Advanced oxidation process was optimized over a period of 60 minutes by changing the ratio of acetic acid t...

water plays a vital and essential role in our ecosystem. this natural resource is becoming scarce, making its availability a major social and economic concern. use of a large variety of synthetic dyes in textile industries has raised an hazardous environmental alert. about 17 - 20% of freshwater pollution is caused by textile effluents. these effluents are recalcitrant to biodegradation and cau...

zno and tio2 nanoparticles wereimpregnated with merbromin dye and used as modified photocatalysts for degradation of phenol. dye-modified zno and tio2 showed significantly higher photocatalytic activity than neat zno and tio2 under visible light illumination. moreover, the prepared dye-modified zno showed superior photocatalytic efficiency in degradation of phenol compared to the dye-modified t...

introduction: basal cell carcinoma (bcc) is the most common cutaneous malignancy. proffered treatment for these lesions is surgery. based on patient’s age, drug allergies, and place of lesions, surgery may not be the best option, and alternative treatments should be considered. pulsed dye laser (pdl) may be a good alternative therapy. the aim of the present study was to determine the effectiven...
