| Abstract | ||
| Adsorbent materials for industrial and environmental applications are the goal of seeking research under active investigation now. Activated carbons could be obtained from the organic material after been chemically or physically treated. In Egypt, Sugarcane bagasse could be considered one of the agricultural wastes that frequently produced. In this study, the low-cost adsorbent was prepared from raw Bagasse. The batch experiment was set up to determine the effect of using the agriculture waste (sugarcane bagasse) without any modification and activated it chemically and physically on methylene blue removal. The influence of adsorbent amount, agitation rate, and temperature on the dye removal were studied. The result shows that the percentage of dye removal reached up to %99.6 when the initial dye concentration was 15 ppm, and the amount of sorbent (chemically activated) was 0.3 g at room temperature. The adsorption kinetics and isotherms for the removal of methylene blue were represented with different models. It was detected that Langmuir and Freundlich's equations have the R2 value closed to unity, and the maximum adsorption calculated capacity was 2.2 mg/g when the initial dye concentration was 15 ppm. Furthermore, pseudo-first-order and pseudo-second-order were fitted to examine the adsorption kinetic, and a pseudo-second-order calculated the highest adsorption rate for the raw bagasse (0.59446 g/mg.min). | ||
