| Summary: | In this study, Saccharum bengalense(SB) was used as biosorbent for the removal of Mn (II) ions from aqueous solution. The influence of biosorbent dose, time, pH and temperature was investigated in the biosorption process. Studies showed that by increasing pH of the solution, metal removing efficiency of Saccharum bengalensefrom the aqueous environment was enhanced but to a specific extent, pH 5.0, at time 50minutes and dose 0.1g/50mL. Langmuir, Freundlich, Harkin Jura and Halsey adsorption isotherm were used to studying adsorption efficiency of Saccharum bengalense. Langmuir and Harkin Jura adsorption isotherms well explained the adsorption process as compared to other isotherms with correlation coefficient 0.943 and 0.968 respectively. At 313K temperature, adsorption capacity (qe) of Saccharum bengalense for removal of Mn (II) ions from aqueous solution was 21.72mg/g. Kinetic study showed that pseudo second order was best followed by the adsorption process with correlation coefficient 0.997. |
