BACKGROUND Annually, large quantities of dyes are produced and consumed in different industries. The discharge of highly colored textile effluents to the aquatic environments causes serious health problems in living organisms. This paper investigates the performance of each of the electro-oxidation and electro-reduction pathways in the removal of reactive red 120 (RR120) from synthetic textile ...

In this work, we investigated the effect of various adsorption parameters (solution pH, temperature, contact time, and presence phosphate nitrate ions) on Reactive Red 120 (RR120) dye by Polyamide Nylon 6 (PN6) microplastics (MPs). Maximum uptake was achieved at pH 2.0, temperature rise from 295 to 313 K resulted in decrease RR120 sorption PN6. Equilibrium after 7 h, kinetic data obeyed pseudo-...

Abstract Fabricating surface oxygen vacancies is considered to be an efficient method improve the adsorption performance of sorbents. In this work, a bismuth oxychloride/biochar (BiOCl/BC) nanocomposite with abundant was successfully prepared by facile ball milling method. BiOCl/BC found have excellent for removing reactive red-120 (RR120) from aqueous solution. The effects key parameters, such...

This paper evaluates the degradation of two azo reactive dyes, C.I. Reactive Yellow 84 (RY84) and C.I. Reactive Red 120 (RR120) by photo-Fenton and Fenton-like oxidation. All experiments were performed on a laboratory scale set-up. The effects of different reaction parameters such as initial pH, contact time, effect of light and hydrogen peroxide concentrations on the oxidation of the dye aqueo...

This research investigates the potential use of pyrite cinder (PC) as an efficient Fenton-like catalyst for removal reactive azo dye Reactive Red 120 (RR120) from aqueous solutions. The characterization its PC structure and composition confirmed great to act catalytic iron source in a heterogeneous Fenton system. Dye optimization was performed terms dosage (0.4–8 g/L), H2O2 concentration (2–25 ...

The elimination of Reactive Red 120 (RR120) from synthetic solution using biochar generated Ulva prolifera was investigated. process parameters sorbent dose (A), pH (B), initial dye concentration (C), and temperatures (D) were optimized response surface methodology (RSM). To estimate the removal effectiveness with best 27 trails, Box-Behnken method (blocked) utilised. Analysis variance (ANOVA),...
