KINETICS OF GASEOUS TOLUENE ADSORPTION ON CANDLENUT SHELL ACTIVATED CARBON
ABSTRACT: Adsorption kinetics
of gaseous toluene
on activated carbon
prepared from candlenut
shell had been studied. The research
was performed by examining adsorption data, which was obtained in previous
research, over several rate equations, which were: (1) Lagergren’s pseudo first
order rate equation, (2) Ho’s pseudo second order rate equation, (3) Elovich’s
equation, and (4) persamaan Ritchie’s equation.
The result showed
that the data
of toluene adsorption
on candlenut shell activated carbon fits the Ho’s pseudo
second order rate equation and, hence, the model is the most applicable model
for the adsorption.
Calculation from linear regression of Ho’s pseudo second order rate equation gave the
equilibrium adsorption capacity value of 56,069 mg g-1, second order rate
constant of 3,54x10–4 g mg-1 min-1, and
initial adsorption rate of 1,112 mg g-1 min-1.
