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.

Crystal violet dye poses significant environmental and human health risks due to its toxicity, persistence, bioaccumulative nature. It contributes potential carcinogenicity, cytotoxicity, systemic toxicity upon exposure. To address this issue, a novel SrCO3/MgO/CaO/CaCO3 nanocomposite was synthesized using the Pechini sol-gel method, producing AE500 AE700 at 500 700 °C, respectively, for efficient removal of crystal from aqueous media.
