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...

«درخت بخشنده» کتابی تصویری از سیلورستاین، نویسندۀ آمریکایی داستان‌های کودک، است. این کتاب به بسیاری زبان‌ها ترجمه شده و مورد خوانش تفاسیر متعددی نیز قرار گرفته با توجه کثرت ترجمه‌های فارسی خوانش‌های گوناگون مفسرانِ آن، اثر مذکور برای موضوع ترجمه‌شناسیِ مقاله اختیار پژوهش پیش‌ِرو روش تحلیلی‌ـ توصیفی در پی پاسخ چگونگی برهم‌کنش سازه‌های غیرکلامی (تصاویر، ریزنقش‌ها، صفحه‌بندی، تایپوگرافی رنگ فونت) پیر...

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...

The photocatalytic degradation of the commercial reactive Black5 (RB5), Blue19 (RB19), Green19 (RG19), Red120 (RR120), and Yellow81 (RY81) in aqueous solution and sunlight were examined in the presence of Fe2O3 and the mixture Fe2O3/H2O2 as catalysts. The results showed that the photocatalytic degradation followed first-order...

Color and organic matter removal from dyehouse effluent remains a challenging issue for the environmentalist textile dyer. Until now, various treatment processes have been proposed with limited success. In this study, dye model industrial pollutant Reactive Black 5 (RB5; 20 mg/L) could be rapidly degraded by persulfate (PS)-enhanced photocatalytic using novel, home-made lanthanum iron oxide (LF...
