“…The synthesis of activated bentonite clay (ABC) involved two distinct activation methods, utilizing sulfuric acid (H 2 SO 4 98%) and sodium hydroxide (NaOH). The activation process incorporated slight modifications based on previous studies [13,30,31]. The BC was initially washed with distilled water to eliminate impurities, followed by drying in an oven at 100 • C and subsequent fine grinding.…”

“…Bentonite clay (BC), recognized for its abundant availability, cost-effectiveness, and remarkable adsorption capacity, has attracted considerable attention as a potential adsorbent for dye remediation [11,12]. Previous studies have highlighted the effectiveness of BC in adsorption and separation, emphasizing its high cation exchange capacity, stability, and strong adsorption capabilities [13,14]. Nonetheless, the realization of BC's full adsorptive potential typically necessitates chemical modifications aimed at augmenting its surface area and the availability of adsorption sites, thereby significantly boosting its performance in dye removal applications [15].…”

This study addresses the urgent need for effective water treatment methods by synthesizing and characterizing activated bentonite clay (ABC) adsorbents to remove methylene blue (MB) from aqueous solutions efficiently. Conventional adsorbents often exhibit limitations in efficiency and regeneration capabilities, necessitating novel approaches to water treatment. The primary objective is synthesizing and characterizing high-quality ABC adsorbents capable of effectively removing MB. The activation process was optimized, and adsorbent performance was evaluated regarding MB removal efficiency and regeneration potential. Various activation dos-ages were investigated, and comprehensive physicochemical characterization was performed using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), BET (Brunauer–Emmett–Teller) analysis, X-ray fluorescence (XRF), thermogravimetric analysis (TGA), and X-ray diffraction (XRD). The synthesized adsorbents demonstrated exceptional MB removal efficiency (99.593%) and impressive adsorption capacity (22.131 mg/g) when activated with 16 M sodium hydroxide. The adsorption process exhibited spontaneity and exothermicity, as validated by Freundlich and second-order kinetic models. Furthermore, the adsorbents showcased successful regeneration and reusability over three cycles, highlighting their potential for long-term application in water treatment. This study significantly advances water treatment by offering a novel approach to MB removal using base-activated bentonite clay (BABC) adsorbents, contributing to the development of sustainable water treatment solutions.
