This study demonstrates the performance and characterisation of Borassus Flabellifer shell derived Nano Composite (BNC) in the adsorption process for the removal of reactive diazo dyes. Borassus flabellifer shell, an agricultural waste material, is evaluated and subjected to activation under CO2...

The kinetic of the degradation of Food Yellow 3 (FY3) and Food Yellow 4 (FY4) dyes by oxidation using hydrogen peroxide 30% in alkaline solution was studied. The kinetics were measured spectrophotometrically by UV–vis at 427 nm for FY4 and 485 nm for FY3 and under a temperature range of 25–70 ...

The decolorization of azo dye C.I. Acid Yellow 23 (AY23) by Fenton process was investigated. The decolorization rate is strongly dependent on the initial concentrations of the Fe2+ and H2O2. The optimum operational conditions were obtained at pH 3.A kinetic model has been developed to predict th...

This study focuses on the investigation of removal of textile dye (Reactive Yellow) by a combined approach of sorption integrated with biodegradation using low cost adsorbent fly ash immobilized with Pseudomonas sp. To ensure immobilization of bacterial species on treated fly ash, fly ash with i...

The commercially available Fe0 aggregate has advantages of low-cost, fast-effective decontamination, reusability, and ease of operation. However, little study has been done on the performance of Fe0 aggregate as a catalyst in degradation of azo dyes, particularly used in persulfate (PS) oxidatio...

The purpose of this study was to investigate the catalytic role of granular activated carbon (GAC) on the degradation and mineralization of two reactive azo dyes (C.I. Reactive Red 194 (RR194) and C.I. Reactive Yellow 145 (RY145) in aqueous solution by treatment with ozone. Decolourization of th...

Enhancing the separation of hole-electron pairs is one of the valid pathway to enhance the photocatalytic degradation performance of semiconductors. In this work, cucurbit[8]uril/zinc oxide (CB[8]/ZnO) composites were prepared. The structure, morphology, surface elements and optical properties o...

The present work aims encapsulating photovoltaic cells in glass reinforced epoxy composite by vacuum resin infusion, incorporating additives directed to enhance the performance stability of the manufactured photovoltaic modules under ultraviolet (UV) exposure.UV absorber (UVA) and hindered amine...

A novel desulfurization approach involving ultrasound, ultraviolet irradiation and additives (catalyst and/or oxidants) was investigated for degradation of thiophene (model sulphur compound) present in n-hexane considered as simulated crude diesel. The approaches based on ultrasonic horn also in...

BackgroundPruritus is one of the common problems in hemodialysis patients that involves more than 45% of Iranian patients. Its exact pathogenesis is unclear. Meanwhile, violet is an old plant with anti-scratching effects, which is extensively used to treat diseases in the Persian medicine. This ...

BackgroundDaylight photodynamic therapy (dPDT) is an effective treatment for field-change actinic keratoses (AK), with similar efficacy to conventional PDT but lower patient pain scores. Whilst AK occur consequent to chronic solar ultraviolet (UV) exposure, paradoxically solar visible radiation ...

Ceria (CeO2) nanoparticles were synthesized by the precipitation method without use of any organometallic precursors. Photocatalytic degradation of reactive dyes such as Reactive Green 19 (RG19), Reactive Orange 84 (RO84), Reactive violet 1 (RV1) and Reactive Yellow 81 (RY 81) were investigated ...

Water pollution is the most threatening issue prevailing in our society these days. Methyl violet is released into the water resources through textile and paint industries. High dye concentration in water inhibits the photosynthesis process thus, affecting the aquatic life. In addition, it indir...

The detection of reactive oxygen species (ROS) using 2′,7′–dichlorofluorescin diacetate (DCFDA) is commonly performed by a single measurement of fluorescence but this fails to capture a profile of ROS generation over time. This study aimed to develop a real-time monitoring method to increase ...

A new magnetically separable visible light active indium doped ZnSNiFe2O4 photocatalyst is synthesized and evaluated for the photodegradation of acid violet 7 (AV-7) dye. Characterization of nanocomposite suggests that indium doped ZnS exists in hexagonal structure, while NiFe2O4 is in the cubic...

Two equilibrium models based on statistical physics, i.e., monolayer model with single energy and multilayer model with saturation, were developed and employed to access the steric and energetic aspects in the adsorption of reactive violet 5 dye (RV-5) on cocoa shell activated carbon (AC) and co...

Immobilized eggshell with a polymer mixture of alginate and polyvinyl alcohol was applied as a biocomposite adsorbent (ESC) for the adsorption of C.I. Remazol Reactive Red 198 from aqueous solution. ESC was characterized using XRD, TGA, FTIR and SEM. The Red dye adsorption onto the ESC was inves...

The exceptional thermal stability of the UiO-67/68-family MOFs makes them ideal candidates to explore post-synthetic functionalization routes aiming to the heterogenization of homogeneous catalysts. We previously demonstrated that a small fraction of the linkers in the UiO-67 MOF can be replaced...
