Many industries use huge amounts of synthetic dyes which may release into the wastewater in dyeing processes causing serious damage to aquatic life as they are recalcitrant, nonbiodegradable, stable oxidizing agents, and toxic. Adsorption on activated carbon has been found be a very efficient treatment method. In this work, new adsorbent material composed aluminum chloride (AC-Al) was prepared ...

This study used a novel integrated technology of ceramic supported carbon membrane (CSCM) to degrade azo dyes through an anaerobic mixed culture. The CSCM worked simultaneously as biofilm support, redox mediator, and nano-filter enhance the dye decolorization efficiency. Acid Orange 7 (AO7) was initially investigated with without microorganisms in both support (CS) reactors. bioreactor (B-CSCM)...

Abstract This study successfully synthesized Li 2 MnSiO 4 /Mn 3 O (LMS/M3) and Mn 0.8 Ni 0.2 SiO (LMNS/M3) nanocomposites in a two-step method first, by preparing (M3) nanoparticles through hydrothermal second, synthesizing (LMS) (LMNS) ethylene diamine tetra-acetic assisted sol–gel method. In the last method, two are mixed hand-milling to form nanocomposites. Synthesized were characterized usi...

As natural fibers, low-cost biosorbents have proven to be an effective and clean tool remove textile dyes from wastewater. In this research, the Reactive Black 5 removal ability of original enzyme-modified fibers were assessed. A fiber extracted a Colombian fique plant (Furcraea sp.) was employed. The effects protonation with different solvents dye solution pH on RB5 evaluated. biosorbent chemi...

Analyses were carried out for adsorption of a reactive dye RB5 onto chitin and chitosan under static and dynamic conditions in an air-lift reactor. Assays were conducted for the effect of the type of sorbent and its content in the reactor on adsorption capacity of sorbents examined. The sorbent’s concentration under static conditions and in the reactor reached 5 mg d.m./dm3. In all experimental...

In this study, the degradation efficiency of Mn-20at%Ni and Mn-30at%Ni particle powders made by melt-spinning high-energy ball-milling techniques is investigated in relation to azo dye Reactive Black 5. SEM, EDS, XRD were used analyze powders’ morphology, surface elemental composition, phase structure. An ultraviolet-visible absorption spectrophotometer was measure ball-milled powder’s capacity...
