This study reports the preparation of a novel hybrid composite and its application in adsorption. For this preparation, zirconia (ZrO2) was precipitated onto an integrated framework reduced graphene oxide (rGO) black cumin (BC) seeds. Characterization using Fourier-transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, energy-dispersive analysis, transmission microscopy confirmed successful incorporation ZrO2 nanoparticles (5–20 nm) into carbon rGO seed powder. The microscopic analysis further revealed that NPs were dispersed throughout rGO-BC framework. Using rGO-BC@ZrO2 composite, methylene blue dye decontaminated from water through batch adsorption process. achieved 96% MB at adsorbent dose 2.0 g/L, nearly 100% when concentration 3.0 g/L. Modeling experimental values also established to verify viability mechanism. Thermodynamic modeling feasibility spontaneity present Isotherm modeling, which showed compatibility with Freundlich isotherm, suggested multilayer demonstrated good persistence reusability for up five consecutive cycles. Thus, presents optimistic results regarding purification.

Abstract Synthetic dyes in wastewater present a challenging problem that requires special attention due to the high environmental risks, and magnetic adsorbents appear as promising alternatives solve it. Magnetic activated carbons (MAC) were prepared by comparing single- multi-step methods. Palm kernel shells used precursors, with ZnCl 2 , then magnetized adding solution containing Fe 3+ ions (FeCl 3 ). Iron compound inclusion aims enhance effectiveness of carbon an adsorbent for liquid waste. Fourier transform infra-red characterization showed functional groups detected on MAC O–H, C═O, C═C, C≡N, C–O. The effect preparation methods dye concentration (10–30 mg·L −1 ) adsorption kinetics investigated. Characterization through pyrolysis (M-MAC) has larger pores, achieving capacity up 6.953 mg·g 28% removal efficiency, making it superior performance. Furthermore, data fitted well Redlich–Peterson isotherm model R = 0.9788 M-MAC, while agreed both pseudo-first-order pseudo-second-order models. Moreover, NaOH successfully recovered desorption efficiencies 98.34%.

The discharge of textile wastewater (TWW) into the environment releases multiple toxic substances that pose a significant threat to aquatic life. Most studies evaluating treatment efficiency focus on removal parameters, such as chemical oxygen demand (COD), total organic carbon (TOC), dissolved (DOC), biochemical (BOD), and colour. One processes has presented high efficiencies in TWW is use biochar (BC) an adsorbing material. BC shown ability remove complex from water since it able decrease content COD, TOC, DOC. However, toxicity treated effluents not been widely studied. In this regard, essential only treatments removing matter but also their reduce WW toxicity. This research evaluates acute real with Pinus patula by using Daphnia pulex sentinel species. For purpose, D. individuals were exposed BC-treated for 48 h, mortality defined absence movement limbs antennas. It was found although P. 120 min eliminated 72.8% initial DOC under optimal conditions (pH 3 13.5 g/L dose), effluent remained toxic, inducing 85.7% 71.4% rates 100% (v/v) 50% dilutions. Despite increase survival rate due protective effect achieved constituents contained reconstituted samples, these findings emphasize necessity conducting before considering after having treated.
