ABSTRACT

The potential feasibility of powdered biomass of Ailanthus   excelsa.  for removal of methylene blue from aqueous solution was investigated. The effects of various experimental parameters such as Biomass dose, Contact time, and concentration of MB solution, pH, and temperature were investigated. The extent of methylene blue removal increased with the increased in contact time, The maximum removal observed at 12 to 15 minutes. The optimum pH is 2. The sorption increases with decreasing temperature. Adsorption data was better fitted to the Langmuir and Freundlich isotherm with the R² values. Langmuir and Freundlich equations were found to have the correlation coefficient value in good agreement. Adsorption of MB onto Powdered Biomasas of Ailanthus   excelsa. followed pseudo second order kinetics with R² value 0.9996. The calculated values of ∆H°, ∆S° and ∆G° were found to be 15.225.17 KJ/mol, -0.04656 KJ/mol and 1.8235 KJ/ mol, respectively. The equilibrium data were also fitted to the Freundlich equation and it was observed that the sorption process is spontaneous and exothermic in nature. The results in this study indicated that the untreated powdered biomass is cheap, easily available, ecofrieindly very good biosorbent for removal of organic dye methylene blue.
