Equilibrium isotherm, kinetic and
thermodynamic studies of the adsorption of erythrosine dye
onto activation carbon from coconut fire was carried out.
The coconut fibre obtain from Elele, Rivers State Nigeria,
was washed, dried, carbonized at 400oC, crushed, sieved
and activated at 800oC, before it was washed and dried at
110oC. Variable influencing factors, such as contact time,
temperature and initial concentration were studied through
single-factor experiment, while other factors are kept
constant (at 30min, 30oC and 50mg/L) in each adsorption
experiment. The Freundlich isotherm fits adsorption
compare to others used, the adsorption kinetic followed
pseudo-second order reaction, while the thermodynamic
parameters, (?H) = 28.73KJ/mol, (?
