Abstract Ly @ FeZn layered double hydroxides (LDHs) controllable fabrication based on Box-Behnken Design (BBD) model was fabricated, and presented stable efficient removal performance for Ciprofloxacin (CIP), Norfloxacin (NOR) Ofloxacin (OFL) removal. It should be noted that had different adsorption behavior towards CIP, NOR OFL. Furthermore, the characterized by SEM, XRD, FT-IR XPS. Results revealed optimized condition (temperature of 60 °C, Fe / Zn molar ratio 0.5 lysine dosage 5.8 mmol) removing efficient. The highest capacity OFL were 193.83, 190.20 62.12 mg/g, respectively. Adsorption kinetics both CIP well simulated with pseudo-first-order kinetic model, while well-described pseudo-second-order. Moreover, thermodynamics indicated processes exothermal, feasible spontaneous. worth noting mechanism synergistic reaction electrostatic attraction, chemical bonding flocculation. On other side, relatively low, only attraction.

Anaerobic digestion is a promising alternative for the valorization of solid waste and wastewater from citrus processing agroindustry, enabling energy recovery by obtaining biofuels, such as hydrogen methane.The co-digestion these substrates proposal to boost sustainable logistics treatment expand potential technicaleconomic feasibility.There need alternatives overcome identified limitations aspects that be better elucidated, operational parameters, system configurations, supplementation, others.In this study, it proposed codigestion liquid agroindustry in two-phase approach, through assays batch reactors obtain evaluate effectiveness fermentative autochthonous inoculum, identify more significative variables process, strategies efficient stable fermentation methanogenesis, optimize conditions enhance production perspective continuous with application leach bed reactor configuration, being investigated parameters allow maximizing degradation recovery.The inoculum was obtained selffermentation waste, its microbial community characterized abundance genera Olsenella, Prevotella, Lactobacillus, Bifidobacterium; did not reach high H 2 production, highest P 142.5 mL.L -1 , Rm 29.8 .h - .Evaluating process supplementation 2.0 g.L buffering agents, an increase 30.2% observed sodium bicarbonate, 176.8% calcium carbonate, compared control assay.The optimized condition 21.4 gTVS.L CPW, 3.4 gCOD.L CPWW, 4.5 CaCO 3 resulting value 0.53 gCaCO /gCHO ratio, 1249.0 mLH .L .For assay relative 95% Clostridium Sensu Stricto 1, inferred Clostridial metabolic pathway predominant, maximum 2230.8 mg.L 1 HBu 1213.6 HAc.For second stage no inhibition substrate concentration, nor limonene (1.5 5.0 ), so lower dilution content resulted higher accumulated methane production.The 99.3% FRC 0.58 gNaCHO .g COD, reaching 6549.7 mLCH 4 allowing 87.1% organic matter removal.In evaluation reactor, significant reduction CPW fixed observed, removal up 79.3%.Furthermore, volumetric HRT 12h phase IV (1609.9mLH .d ); however, yield 24h (104.9 CHO).The main soluble metabolites produced were caproic, butyric, acetic acids, ethanol, Caproicoproducens, Bifidobacterium, Solobacterium microorganisms abundance.Therefore, found prospects valuing anaerobic are positive, results contribute development circular economy model chain.
