Red mud modifying by rice husk char (HM105) was sucessfully fabricated through activation of red mud slurry (RM) by rice husk char (RH). HM105 was then characterized by scanning electron microscopy, energy-dispersive X-ray spectroscopy, and X-ray diffraction and employed as an adsorbent for the removal of methylene blue (MB) from aqueous solutions. Some impact parameters on the adsorption of MB as contact time and initial concentration were studied. The results showed that the removal of MB on HM105 was the highest at 90 min and initial concentration of 200 ppm and adsorption data well fitted with Langmuir adorption isotherm model with the maximum adsorption capacity of HM105 was 220.26 mg/g. It demonstrated that HM105 was potential adsobent for treatment of MB as well as other dyes in wastewater.Downloads
