This study presents a sustainable approach to water dye decontamination using monoliths constructed from candlenut shells, clay, and molasses as binder. The shells were activated form carbon then mixed with natural clay create the monolith composite. dough was pushed through stainless-steel mold featuring seven circular openings, each measuring 2 cm in width thickness, (MCC MMCC). rigorously tested for adsorption efficiency, isotherm behavior, kinetic properties. Results showed high removal 92% methylene blue 74% methyl orange, which attributed stronger interaction of negatively charged surface monoliths. analysis followed Langmuir model, indicating monolayer on uniform active sites. Kinetic studies linear regression aligned pseudo-second-order that chemical controlling factor rate. Characterization Scanning Electron Microscopy (SEM) revealed porous morphology, while X-ray Diffraction (XRD) identified crystalline structures present. Fourier Transform Infrared Spectroscopy (FTIR) confirmed presence functional groups essential adsorption, Brunauer-Emmett-Teller (BET) determined specific area pore size distribution. In conclusion, this underscores viability shell clay-derived efficient environmentally friendly adsorbents wastewater treatment, providing practical solution pollution.

Methylene blue dye, commonly used in various industries, poses significant risks to both human health and the environment due its persistence, toxicity, potential disrupt aquatic ecosystems. Exposure can cause severe conditions such as methemoglobinemia, while stability solubility allow it persist natural water systems, reducing oxygen levels harming life. In this study, novel analcime/sodium magnesium aluminum silicon silicate nanocomposites (Z1 Z2) were synthesized via a controlled hydrothermal method, where Z1 Z2 absence presence of polyethylene glycol template, respectively. X-ray diffraction (XRD) analysis confirmed formation crystalline phases analcime sodium silicate. The average crystallite size nanocomposite is 75.30 nm, whereas exhibits smaller 60.27 nm template effect. Field emission scanning electron microscopy (FE-SEM) revealed that exhibited more uniform well-dispersed particles compared Z1. Energy-dispersive spectroscopy (EDX) elemental composition, showing higher content optimized incorporation Z2. High-resolution transmission (HR-TEM) demonstrated had well-defined spherical particles, indicating improved structural control. maximum adsorption capacities 230.95 mg/g for 290.69 process was exothermic, spontaneous, chemical nature, following pseudo-second-order kinetic model Langmuir isotherm, confirming monolayer on homogeneous surfaces.
