Abstract :
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 bengalense from 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.
