background and purpose: azo dyes including direct blue 71 (db71) are toxic, mutagenic and carcinogenic contaminants in effluents of industries. this study aimed to investigate the adsorption of db71 from aqueous solution onto pistachio hull waste (phw) as a low-cost adsorbent. materials and methods: a series of experiments were performed via batch adsorption technique to examine the effect of t...

In the present work, the activity of sono-catalytic synthetic nano-sized ZnO powder was studied via degradation of Direct Blue71 (DB71), an organic compound, as a case study. Nano-sized ZnO powder was synthesized without high-temperature activation then introduced to act as the sono-catalyst. Different characterization analyses were applied to demonstrate and confirm the structure of synthetic ...

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...

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)...

In the present work, we have investigated the sorption efficiency of the treated activated carbon from walnut shell(ACW) towards Direct Red 81 (DR81) and Direct Blue 71 (DB71) for the removal from aqueous solution. Thesorption study of ACW at the solid-liquid interface was investigated using kinetic, sorption isotherms, pH effectand amount of adsorbent. Experimental data were analyzed by Langmu...

• Homogalacturonan pectins mainly inhibit TLR2-1. Pectins with a low DM or intermediate high DB inhibited TLR2-1 strongest. TLR2 bound strongest to an DB. inhibiting also IL-6 secretion from macrophages. have anti-inflammatory effects via Toll-like receptor (TLR) inhibition in degree of methyl-esterification-(DM)-dependent manner. However, vary distribution methyl-esters over the galacturonic-a...
