The Removal of Methylene blue Dye by Using Adsorbent Material Prepared from􀀃Ceratophyllum demersum L.

Abstract

In the research, the Ceratophyllum demersum L was used as an adsorbent for methylene blue dye removal. The effects of adsorption parameter such as adsorption time, initial dye concentration, acid-base of solution and temperature during adsorption process were investigated. It was found that adsorption equilibrium state was completed within 7 hours. The suitable pH, adsorbent dosage and adsorption temperature were higher than 6, 0.1 g and 50 oC, respectively. In addition, the adsorption isotherm of the dye fitted well with the Langmuir model (R2 = 0.983), demonstrating that Ceratophyllum demersum L might be applied for a good adsorbent for dyes from wastewater
