Potential of Easily Prepared Low-Cost Natural Clay for the Cationic Adsorption of Methylene Blue Dye

Thisstudy aims to synthesize and analyzethe characteristics of natural clay as an adsorbent for cationic methylene blue, which can be easily manufactured as a low-cost natural clay powder. Natural clay was prepared and subsequently analyzed using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and X-ray fluorescence (XRF). The adsorption of methylene blue was evaluated using a batch approach, followed by examination by UV-Vis spectrophotometry. The adsorption data will then be analyzed for kinetic performance. The findings indicated that the methylene blue adsorption capability of natural clay reaches 72.51%. The kinetic investigation of methylene blue adsorption utilizing natural clay indicated that the adsorption process conformed to the Pseudo Second Order kinetic model.
