| dc.description.abstract | The objective of this study is to compare methylene blue dye removal ability by 3 types of lowcost
adsorbent including activated carbon charcoal and bamboo charcoal. The effects of adsorbent
dosage (0.5-2.0g), contact time (0-120min), initial methylene blue concentration (65-140mg/g) and pH
solution (3-9) were investigated. The adsorption isotherms were analyzed by using Langmuir and
Freundlich equations. The experimental results found that the optimum adsorbent dosage and contact
time of the low-cost adsorbents were 2 g and 90 min, respectively. The removal efficiencies of
methylene blue by Activated carbon, Charcoal and Bamboo charcoal were 75.48, 23.90 and 16.57 %,
respectively. Adsorption data were fit to Langmuir isotherm model. The maximum adsorption capacities
of activated carbon, charcoal and bamboo charcoal were 18.73, 5.18 and 0.81 mg/g, respectively.
Therefore, Activated carbon could be an effective adsorbent for methylene blue dye removal. | en_US |
