| Abstract: | In the research, the Ruzi grass (Brachiaria ruziziensis) was used as an adsorbent for methylene blue dye removal. The effects of adsorption parameter such as adsorption time, acid-base of dye solution and adsorbent dose were investigated. It was found that adsorption equilibrium state was completed within 6 hours. The suitable pH, adsorbent dosage and adsorption temperature were higher than 6, and 0.5 g, respectively. In addition, the adsorption isotherm of the dye fitted well with the Langmuir model with the maximum adsorption capacity of 14.01 mg/g and the adsorption kinetics study showed that the adsorption of dye onto the adsorbent could be best described by the pseudo second-order model. The overall result demonstrating that Ruzi grass might be applied for a good adsorbent for dyes from wastewater. |
