Abstract

Methylene blue is an organic pollutant found in industrial effluents that is very toxic to humans and the environment. This study used 8-hydroxyquinoline-modified bentonite adsorbent to remove methylene blue from aqueous solutions. In the present work, different doses of modified bentonite were used as a new adsorbent for the removal of methylene blue. The effects of contact time, pH, adsorbent dose, and initial methylene blue concentration were recorded. Then, the adsorption data were described with Langmuir and Freundlich adsorption isotherms. The highest percentage of methylene blue adsorption was observed at pH = 7.5. The optimum amount of adsorbent was 0.1 g.L-1 and after 120 minutes, the process reached an equilibrium state. The adsorption of methylene blue increased following an increase in the pH of the solution. It was also observed that the contact time significantly affected the rate of methylene blue adsorption. The experimental data fit much better in the Freundlich (R2 = 0.999) model than the Langmuir (R2 = 0.992) model. So, 8-hydroxyquinoline-modified bentonite has the potential to be utilized for the cost-effective removal of methylene blue from aqueous solutions.

Modified bentonite as adsorbent material for the removal of the basic dye methylene blue from aqueous solutions

Highlights

  • Methylene blue can be successfully adsorbed (96.3%) by 8-hydroxyquinoline modified bentonite in batch design.
  • Langmuir and Freundlish models provide information on maximum sorption capacity.
  • The maximum adsorption capacity was 526.3 mg.g-1 with 100 ppm initial concentration of methylene blue, 120 minutes of contact time, and 0.1 g of modified bentonite sample.
  • Modified bentonite has proven to be a promising economic material and recommended for the simultaneous removal of cobalt and methylene blue from aqueous solutions.
