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.

Abstract Conventional wastewater treatment processes are often unable to remove antibiotics with resistant compounds and low biological degradation. The need for advanced sustainable technologies from water sources seems essential. In this regard, the effectiveness of a spinning disc photocatalytic reactor (SDPR) equipped visible light-activated Fe 3 O 4 @SiO 2 -NH @CuO/ZnO core–shell (FSNCZ CS) thin film photocatalyst was investigated decomposition amoxicillin (AMX), representative antibiotic. Various characterization techniques, such as TEM, FESEM, EDX, AFM, XRD, UV–Vis-DRS, were employed study surface morphology, optoelectronic properties, nanostructure FSNCZ CS. Key operating parameters irradiation time, pH, initial AMX concentration, rotational speed, solution flow rate fine-tuned optimization. results indicated that highest (98.7%) attained under optimal conditions 60 min speed 350 rpm, 0.9 L/min, pH 5, an concentration 20 mg/L. Moreover, during more than 69.95% chemical oxygen demand 61.2% total organic carbon removed. After AMX, there is substantial increase in average oxidation state SDPR 1.33 1.94 3.2, respectively. Active species tests confirmed ·OH ·O − played dominant role decomposition. developed SDPR, which incorporates reusable robust CS photocatalyst, demonstrates promising potential compounds.

Sugar cane bagasse (SB) was modified with cetyltrimethylammonium bromide (CTAB), followed by impregnation zinc oxide (ZnO) to create a synergistic adsorption and photocatalytic system for methyl orange (MO) methylene blue (MB) removal. The presence of CTAB ZnO confirmed X-ray diffraction, Fourier transform infrared, energy dispersive (for Zn O). Modification SB (CSB) generated more positive sites on the surface SB, which enhanced MO removal compared that pristine SB. induces decrease in due CSB surface, might reduce CSB. In addition, can interact Zn2+ O2– form lead contrast, facilitated good MB CSB, indicating process plays greater role removing MB. However, addition H2O2 improve under irradiation formation external •OH. performance also observed be favored acidic alkaline conditions, respectively.
