Reactive Black 5（RB5）またはReactive Orange 16（RO16）を32 mg/L含む合成廃水を2 Lバッチリアクターでオゾン処理した。RB5とRO16を含む廃水の色度は、オゾン処理（6.3 g－O3/m3, 4 L/min）によって、8分間でそれぞれ835から50、2780から750に減少し、15分間で両者とも検出下限の50未満になった。一次脱色速度定数はRB5が0.35 min－1、RO16が0.47 min－1であった。活性汚泥微生物を用いた生分解試験では、オゾン処理により染料廃液のBOD濃度が増加することが示された。RB5含有廃水の全有機物（TOC）濃度は、生分解単独で8.9 mg/Lから8.4 mg/L、オゾン処理単独で5.8 mg/L、オゾン処理と生分解によって3.3 mg/Lとなった。RO16含有廃水のTOC濃度は、生分解単独で13.9 m...

UNLABELLED Although Mn(2+) is the most abundant substrate of versatile peroxidases (VPs), repression of Pleurotus ostreatus vp1 expression occurred in Mn(2+)-sufficient medium. This seems to be a biological contradiction. The aim of this study was to explore the mechanism of direct oxidation by VP1 under Mn(2+)-deficient conditions, as it was found to be the predominant enzyme during fungal gro...

industrial wastewater included the dyes one of the important sources of environmental pollution that founded in loom wastewater which are harmful for human health and environment. therefore, the purpose of this research was investigated removal of rb5 dye from aqueous solution by using of adsorption onto activated red mud as an cheap adsorbent. this research was experimental- laboratorial study...

Decolorization of Reactive Black 5 (RB5) was investigated by heterogeneous photocatalysis using N-doped TiO2. TiO2 photocatalysts were synthesized means a sol-gel process. X-ray diffraction performed the characterization samples, scanning electron microscopy and photoelectron spectroscopy measurements. Photocatalytic activity samples assessed following decolorization degradation efficiency RB5....

in this study, decolorization of the diazo dye, reactive black 5 (rb5) in a coprinus cinereus peroxidase-catalyzed reaction has been investigated. a bisubstate kinetic model for the reaction rate based on the ping-pong mechanism was assumed for the enzymatic decolorization. experimentswere conducted at different rb5 and hydrogen peroxideconcentrations in a batch mannerto estimate the intrinsic ...

In this work, the degradation performance of Fe2+/PAA/H2O2 on three typical pollutants (reactive black 5, ANL, and PVA) in textile wastewater was investigated comparison with Fe2+/H2O2. Therein, had a high removal RB5 (99%) mainly owing to contribution peroxyl radicals and/or Fe(IV). Fe2+/H2O2 showed relatively PVA (28%) resulting from ·OH. comparative removals ANL. Additionally, more sensitive...

The removal of the azo dyes Orange II (OII) and Reactive Black 5 (RB5) from aqueous solutions was studied using three types adsorbents derived chitosan: unmodified chitosan beads (un-Ch), tuned with a deep eutectic solvent (DES) composed choline chloride:urea at 1:2 molar ratio (Ch-DES), along FeO nanoparticles added to modified DES (Ch-FeO-DES). Both were effectively removed in 3–4 h when Ch-D...
