Performance assessment of adsorbents based on natural bentonite for removal of cationic dye

Year: 2023

Type: article

Abstract: The development of safe and cost-effective methods for the treatment of dye polluted wastewater has been a great concern.Herein, Adsorption of methylene blue from aqueous solutions onto modified clay has been investigated.Three adsorbants were prepared through the treatment of a natural Algerian bentonite (NAB) by sodium (Na-Clay), calcium (Ca-Clay), and sulfuric acid solution (Hs-Clay), respectively.The accomplished materials was performed by X-ray diffraction and Fourier transforminfrared (FTIR).The effects of differents process parameters such as contact time, pH of dye solution, initial concentration of dye, and adsorbent amount on the removal efficiency of methylene blue (MB) from aqueous solution were evaluated by batch experiment.The maximum adsorption capacity of 220.28 mg/g reached by Na-Clay.Furthermore, all the prepared adsorbents also displayed a prominent efficiency in removal of cationic dyes.The findings reveal the feasibility of facile clay modification to be used as a potential and rapid low cost adsorbent for removal of cationic dyes from wastewater.
