In this study, a combined process of reduction and adsorption for the degradation azo dye with nanocrystalline Fe80Si10B10 powder as reducing agent is analyzed. A mechanical alloying technique produced powdered alloys needed redox process. The synthesized structure favors efficiency step Reactive Black 5 (RB5) dye. According to UV-Vis analysis, reductive alone allowed nearly complete color remo...

The textile industry generates a large volume of chemically diversified effluents containing, among other compounds, dyes. Untreated wastes are contaminants to surface water, soil, and groundwater. In this aspect, various studies have explored the issue contamination alluvial soils in Alto Capibaribe region, northeast Brazil, due local activity. This inserted into Brazilian semiarid suffers fro...

In this work, a flow photoreactor was designed and set up using low-cost recyclable parts to develop chemical treatments based on advanced oxidation processes (AOP) of highly colored textile wastewater. To evaluate sustainable system´s efficiency, we investigated compared the performance three types destructive methods (UV/H2O2, Fenton, photo-Fenton) decolorization aqueous solutions Reactive Bl...

The novel and intriguing role of Fe(NO3)3 as a chemical activator in carbonization macadamia nutshell is introduced this work. Magnetic mesoporous carbon was achieved by activation with under nitrogen atmosphere at 850°C (MMC-850). Porosity MMC-850 included SBET 317 m2/g Vmicro 0.0796 cm3/g considerably high Vmeso 0.4318 cm3/g. Not only did possesses good magnetic properties saturation magnetiz...

Adsorbent made by carbonization of biomass under oxygen-limited conditions has become a promising material for wastewater treatment owing to its cost-effective, simple, and eco-friendly processing method. Ultrasound is considered green technique modify carbon materials because it uses water as the solvent. In this study, comparison Reactive Black 5 (RB5) adsorption capacity between biochar (BC)...

Abstract A study has been performed on the degradation of Reactive Black 5 (RB5) as pollutant using iron electrode (Fe.S) derived from sludge steel waste via electrochemical method. The Fe.S and titanium graphite electrodes were applied anode cathode respectively during studied. studied operating parameters effect current density, initial pH, concentration, reusability electrode. experiment was...

Herein, two sunlight responsive photocatalysts including TiO2 nanoparticles (NPs) and TiO2/graphene quantum dots (GQDs) nanocomposite for degrading a textile dye, Reactive Black 5 (RB5), were prepared. The results showed that 100% of 50 ppm RB5 could be degraded by NPs TiO2/GQDs within 60 30 min irradiation, respectively. Hence, much better photocatalytic activity in degradation was achieved un...

A continuous compact membrane bioreactor consisted of ceramic-supported graphene oxide (CSGoM) was implemented for the first time anaerobic biodecolorization monoazo Acid Orange 7 (AO7), diazo Reactive Black 5 (RB5), and triazo Direct Blue 71 (DB71) solutions, showing excellent decolorization potential. The prepared by vacuum filtration various solutions using a UF ceramic flat element. efficie...
