The extensive use of crystal violet (CV) dyes may cause water pollution. A highly porous and functionalized activated carbon can be used for adsorption CV dyes. Activated was prepared from oil palm fronds through microwave-assisted pyrolysis activation with phosphoric acid (H3PO4) removal dye wastewater. physico-chemical characteristics (OPFAC) employed by Brunauer-Emmett-Teller (BET) surface area analysis, Fourier transform infrared (FT-IR) Scanning Electron Methodology-Energy Dispersive X-Ray (SEM-EDX) thermogravimetric analysis (TGA), point zero charges (pHpzc). parameters such as pH (4, 7, 10), dosage (0.02, 0.06, 0.1 g), contact time between absorbent adsorbate (2, 5, 8 mins) were optimized using the response methodology-Box-Behnken design (RSM-BBD). experimental results showed that optimum conditions OPFAC 0.1g dosage, 9, 5 min percentage is 91.4%. capacity well fitted pseudo-second-order (PSO) kinetic model. maximum (qmax) Langmuir isotherm 188.4 mg/g. study described Freundlich model coefficient correlation (R2 = 0.9488) describe occurred multilayer onto heterogenous site. thermodynamics indicated process spontaneous endothermic condition values ΔH° (21.86 KJ/mol) ΔS° value (87.90 J/mol K) positive.

Abstract Palm Peat (PP), the world’s first rich lignocellulosic medium derived from date palm agricultural residues, has not been previously explored for environmental purification. This study evaluates PP's performance in adsorbing methylene blue (MB) dye. PP is characterized by a spongy, porous structure with surface area of 16 m 2 /g. It possesses significant carbon and oxygen composition features active functional groups. Under conditions 30 mg/L initial MB concentration, 1 g/L dose, T = °C, pH 7, 900 rpm stirring speed, achieved 68.26% removal efficiency within 90 min. Although higher temperatures enhanced efficiencies, room temperature (30 °C) was chosen subsequent experiments to assess adsorption under ambient minimize energy consumption. Stirring speeds exceeding reduce efficiency, likely due shear forces disrupting interaction between molecules or causing desorption adsorbed dye molecules. Response methodology combined central composite design employed optimize dosage, solution pH. optimum conditions, 97.89% removal. exhibited strong stability over five cycles. Adsorption occurs via π-π stacking, hydrogen bonding, hydrophobic-hydrophobic interactions, electrostatic process being endothermic following Langmuir isotherm model pseudo-second-order kinetic model. The studies across different water matrices revealed lowest degradation rate drain matrix. 71.5% 48.16% TOC real textile wastewater.

Trametes cingulata: A white rot fungus in decolorization of azo dye reactive red 239

Journal of Chemical Technology & Biotechnology, Год журнала: 2025, Номер unknown

Опубликована: Янв. 8, 2025

Abstract Background Azo dyes in textile effluents represent a particular health concern because they include azo groups (NN), which are reactive with DNA nucleic acids. The enzymes produced by white rot fungi can biodegrade broad range of environmental contaminants. This work addresses this concentrating on novel and effective optimal conditions for Trametes cingulata to produce oxidative the capacity decolorize dye red 239. Results A multifactorial experimental design optimized enzymatic activity decolorization. Concentrations 2.5 g L −1 copper sulfate (CS) 3.0 yeast extract (YS) 16 days 100% decolorization, 7.72 U mL laccase (Lac) 0.013 lignin peroxidase (Lip). These were found be ideal decolorization process. maximal Lac was 12.22 CS, 25.0 YS days, addition 0.14 Lip 59% It possible ascertain that dye's functional had been adsorbed fungal mycelium employing Fourier transform infrared spectroscopy. Images obtained from scanning electron microscopy analyses enable distinction certain features signify adsorption Additionally, under conditions, 55% chemical oxygen demand decrease noted. Conclusion findings reported show T. may containing using two distinct processes: biosorption degradation. © 2025 Society Chemical Industry (SCI).
