Adsorption Isotherm Study and Factor Affected on Methylene Blue Decolorization using Activated Carbon Powder Prepared Grapevine Leaf

One of the methods of color removal is adsorption using natural adsorbents. Aadsorption process because of lower cost, easy operation and hide sensitive to toxic substances than other methods is a priority. So, the aim of persent study was to adsorption isotherm and factor affected on Methylene Blue decolorization using activated carbon powder prepared Grapevine Leaf.
This experimental study with differnet parameters such as initial concentration of MB, adsorbent dosage and contact time on the MB adsorption in the batch system were investigated.
Results showed that the adsorption efficiency was achieved to 100% at 10 and 100 mg/L of MB when the amont of adsorbent was 2 g/L with contact time of 90 and70 min at pH=7. Adsorption process could be follow of both Ferndlich (R2= 0.994) and Langmuier (0.984) isotherm which that by Ferndlich isotherm, maximum dye adsorption was calculated to 25.77 mg/g.
Based on the obtained results it can be concluded that activeted carbon prepared of grapevine leaf has high capacity for Methylene Blue dye from aqueous solution.
