The Amberlite IRA-900 resin was tested to remove C.I. Reactive Black 5, C.I. Reactive Red 2 and C.I. Reactive Red 120 dyes from solutions. Batch adsorption studies concerning effects of the phase contact time, pH, temperature, the presence of salts and surfactants were run. A pseudo second-order...

Micrococcus glutamicus NCIM-2168 exhibited complete decolorization and degradation of C.I. Reactive Green 19A (an initial concentration of 50 mg l−1) within 42 h at temperature 37 °C and pH 8, under static condition. Extent of mineralization was determined with total organic carbon (TOC) and ch...

The biosorption of C.I. Reactive Black 5 (RB5) from aqueous solution, using the brown seaweed, Laminaria sp., was investigated in both batch and column modes of operation. Protonation of the native Laminaria biomass, with 0.1 M HCl, considerably improved its RB5 biosorption capacity. Evidence fr...

An activated alumina-supported iron oxide-composite (denoted as FeAA-25) was utilized successfully as a catalyst for the heterogeneous photoassisted Fenton degradation of the azo dye C.I. Reactive Black 5 (RB5) at a pH of 7.0 in our previous study. In this work, the adsorption and desorption beh...

The removal of C.I. Acid Black 210 dye from highly concentrated solutions was studied using a coagulation/flocculation process. Aluminium sulphate was used as a primary coagulant and five commercial polymers were used as flocculant aids. The five commercial polymers were ACCEPTA 2058 (poly-diall...

The reactions of the C.I. Reactive Black 5 with short lived eaq−, OH radical and H atom intermediates of water radiolysis in aqueous solution were investigated by pulse radiolysis with kinetic spectroscopic detection. The transients formed with the three intermediates have absorption maxima at ∼...

This study was performed to investigate the variables that influence the efficiency of color removal from a solution containing an azo dye (C.I. Reactive Black 5, abbreviated here as RB5) by the combination of ozonation and electrocoagulation at iron electrodes. Several working parameters, such ...

Decolorization of the azo dye C.I. Reactive Black 5 (RB5) in solution by a combination of sonolysis and ozonation was investigated. The results showed that the optimum pH for the reaction was 11.0, and both lower and higher pH decreased the decolorization rate. Increasing the initial concentrati...

The removal of color from synthetic wastewater containing Reactive Black 5 was experimentally investigated using direct current electrocoagulation at iron electrodes. The effects of operational parameters such as current density, initial pH, electrolysis time, initial dye concentration and solut...

In spite of the considerable efforts invested to understand the environmental health and safety (EHS) impacts of ultrafine particles, such as the representative PM2.5, there are still significant knowledge gaps to be filled. No conclusive understandings have been obtained about the physicochemic...

In this study, cobalt molybdate (CoMoO4) nanoparticles were synthesized by precipitation and microemulsion methods. The effective parameters for these two methods were determined and optimized using Taguchi design method. The obtained nanoparticles were characterized by XRD, SEM, TEM, DLLS and B...

Arsenic in drinking water is a worldwide public health problem due to its pathogenic induction of oxidative stress in various organ systems. Phytochemicals present in polyphenolic-rich fruits such as black raspberries (BRBs) have diverse health benefits, including antioxidation and modulation of...

Bacteria were isolated from effluents of textile industries and screened by their capability to decolorize at least one of eight reactive dyes used in the textile industries. Three isolates having the capability to decolorize the highest number of dyes with more than 25% of decolorization were i...

BackgroundTreatment-seeking men with alcohol use disorder (AUD) classically exhibit a blunted hypothalamic-pituitary-adrenal (HPA) axis response to pharmacologic and behavioral provocations during the early phases of abstinence from alcohol. Independent of alcohol, a significant muting of HPA ax...

Cotton fabrics dyed with Reactive Black 5 (RB5) was electrochemically stripped using Ti/TiO2-RuO2-IrO2 anode in water, pyridine and phenol solution. The results showed that RB5 dye could be easily stripped from the surface of cotton fabrics through the cleavage of chromophoric group (NN) under t...

In the present work, a commercial activated carbon was impregnated with MnO2 through a facile and efficient one-pot synthesis method. The impregnated carbon was characterized for the Mn content, the textural characteristics, the surface chemistry and the efficiency for removal and degradation of...

Effective effluent treatment is a paramount step towards conserving the dwindling clean water resources. The present study describes the use of crude protease extract from Bacillus Cereus Strain KM201428 biotransformation of azo dye Reactive Black 5 (RB5). Batch experimental results displayed ov...

Heterogeneous photocatalysis using semiconductor oxides as a photocatalyst is an intensely employed technique in photodegradation processes under UV irradiation. More recently, plasmonic photocatalysis came in as a technique that promotes intensification of photodegradation processes, in additio...

Mercury is one of the elements which had attracted the attention of the chemists and physicians of ancient India and China. Among the various metal based drugs which utilize mercury, we became interested in the red sulfide of mercury which is known in ancient Indian literature as rasasindur (ali...
