Phosphate adsorption studies using carbon prepared from stem bark of Eucalyptus teriticornis Smith
Removal of phosphate ions was studied using carbon prepared from stem bark of Eucalyptus teriticornis Smith (family Myrtaceae), from aqueous solution. Study was carried out in the batch technique: as a function of contact time, phosphate concentration, temperature and pH of the solution. Equilibrium time for studied concentrations was not same. The sorption process follows reversible first order kinetics and fits Langmuir sorption isotherm. The forward rate constants increased with decrease in concentration. Maximum sorption was observed at lower temperature and higher pH. Nature of sorption was exothermic and this was supported by K-d values. Desorption study and effect of other ions are also studied.
