Kinetika Adsorpsi Ion Logam Pb (II) pada Karbon Aktif dengan Gelombang Ultrasonik
ABSTRACT: Adsorption capacity
Increase of the activated carbon can be done with the use of ultrasonic
energy-producing high chemical. Activated carbon is used to absorb the metals
Pb(II) with a variety of time. Research purposes to determine the effect of
variation of contact time on the adsorption of Pb(II) using rice husk activated
carbon irradiated with ultrasonic waves and without irradiation. Determining
the reaction kinetics model (reaction order and k values) of Pb (II) using rice
husk activated carbon irradiated with ultrasonic waves. The results showed the
optimum time on the adsorption process of Pb(II) by rice husk activated carbon
is irradiated with ultrasonic waves were 50 minutes, whereas the adsorption
process of Pb (II) by rice husk activated carbon without irradiated with wave
ultrasonic is 30 minutes. Reaction kinetics of Pb(II) according to the
pseudo-second-order kinetic model and the value of k2 = 0.0472 g. mg-1.min-1.
