Congo red dye is classified as a toxic chemical and can be harmful if ingested, inhaled, or in contact with the skin eyes. It cause irritation, allergic reactions, sensitization some individuals. Thus, this paper, CaFe2O4 nanoparticles were produced by simple Pechini sol-gel approach used an adsorbent material for efficient disposal of from aqueous solutions. The maximum adsorption capacity towards 318.47 mg/g. Furthermore, synthesized exhibit average crystal size 24.34 nm. Scanning electron microscopy (SEM) examination showed that are basically ball-like particles mean grain 540.54 Moreover, transmission (TEM) sample revealed aggregated spherical diameter 27.48 Energy-dispersive X-ray spectroscopy (EDS) pattern reveals composed Ca, Fe, O elements, atomic ratio 1:2:4 these respectively. chemical, spontaneous, exothermic, perfectly aligned pseudo-second-order kinetic model, exhibited excellent conformity Langmuir equilibrium isotherm.

The rapid growth of industrialisation has led to the discharge harmful effluents into water bodies, severely disrupting balance ecosystems. detection and removal dyes from wastewater remains a significant challenge. In this study, we report synthesis zinc oxide (ZnO) its doped derivatives through facile chemical method, followed by comprehensive characterisation analysis assess their potential in various applications. structural properties synthesised materials were confirmed X-ray diffraction (XRD), which verified crystalline nature phase purity. Morphological using field emission scanning electron microscopy (FE-SEM) coupled with energy dispersive (EDAX) revealed well-defined nanostructures uniform elemental distribution. adsorption ability synthesized adsorbents was investigated electrochemical methods, cyclic voltammetry Tafel plots, demonstrated enhanced conductivity charge transfer characteristics. Additionally, theoretical studies molecular modelling dynamic simulations employed elucidate interactions between Congo red molecules surface compounds. Adsorption experiments conducted evaluate efficacy ZnO variants as adsorbents. To investigate any or functional changes after dye FTIR XRD compared, provided deeper insight mechanism. This multi-faceted approach highlights ZnO-based for effective treatment other environmental

An excessive accumulation of crystal violet dye in the human body results an accelerated heart rate, tetraplegia, eye irritation, and long-term damage to transparent mucous membrane that protects eyeballs. Accordingly, this paper, sodium manganese silicate/sodium silicate hydroxide hydrate was easily fabricated as a novel type nanostructures for successful disposal from aqueous solutions. The formed after hydrothermal treatment gel produced interaction Mn(II) ions with Si(IV) at 180 °C 6, 12, 18, 24 h were abbreviated MS1, MS2, MS3, MS4, respectively. XRD showed average crystallite size MS4 samples is 8.38, 7.43, 4.25, 8.76 nm, BET surface area 41.58, 46.15, 58.25, 39.69 m2/g, consist spherical irregular shapes grain sizes 157.22, 88.06, 43.75, 107.08 best adsorption conditions employing products achieved pH = 8, contact time 140 min, solution temperature 298 kelvin. linear pseudo-2nd-order model well Langmuir isotherm better describe using adsorbents. studied thermodynamic parameters indicated adsorbents spontaneous, exothermic, chemical. maximum capacities towards are 342.47, 362.32, 411.52, 310.56 mg/g,
