| Abstract/Description: | This study investigated the technical feasibility of using the tobacco stems biomass (TSB), as a low-cost novel adsorbent for removal of methylene blue (MB) from water. TSB was characterized by pH zero-point-charge (pHZPC) and FTIR analysis. Batch adsorption studies were performed to evaluate process variables, kinetics and equilibrium of MB adsorption. Results showed that MB removal was higher at pH values >pHZPC of adsorbent, and for particle size <0.5 mm. The adsorption kinetics followed pseudo-second order (k250.008 to 0.001 g mg21 min21), with intraparticle diffusion as one of the rate limiting steps. The Langmuir isotherm with maximum capacity of 169.5 mg g21 was statistically found a best fit model. A single stage batch adsorber was designed and quantity of TSB required for treating 1000-10,000 L of stained water was determined. The results imply that the TSB with could be a promising alternative adsorbent for remediation of cationic dye bearing wastewater.
