Study on Adsorption of Methylene Blue on Composite Attapulgite Material

    Graphical Abstract
    • Abstract
  • Batch experiments were carried out to investigate the adsorption of methylene blue on attapulgite composite material.The influence of adsorption time,adsorbent dosage,initial concentration,pH,temperature an adsorption-reqeneration of Methylone Blue were studied.The results showed that the adsorption of methylene blue on attapulgite composite material achieved equilibrium through 1.5h.At 30℃,the initial concentration of solution 20mg/L,the adsorption rate can reach 99.36%.The adsorption isotherms could be modeled by Langmuir equation.The adsorption rate could be described by quasi-second-order kinetics equation.Attapulgite composite material has high recycling rate after regeneration.
