Isotherm Dan Kinetika Adsorpsi Logam Cu Menggunakan Adsorben Serbuk Kulit Udang Dengan Variasi Konsentrasi Adsorbat Dan Ph Larutan

ABSTRACT
Adsorption is a process in which solute liquids accumulate on the adsorbent
surface and form a thin layer of atoms or molecules. The adsorbent used was shrimp shell
powder.Utilization of the adsorption process in the absorption of Cu metal is useful for
determining the isotherm model and adsorption kinetics. In this study the adsorption
process was carried out by varying the concentration of adsorbate (10, 20 and 30 ppm)
and the pH of the Cu metal solution (5, 7 and 9) at room temperature. The largest
adsorption capacity occurred at the adsorption pH of 5 and the initial solution
concentration of 10 ppm with an adsorption capacity value of 88.28%. The isotherm
model of the Cu metal adsorption process follows the Harkins Jura isotherm equation
with R2 value of 0.9990. The kinetics of the Cu adsorption process followed the Elovich
kinetics model with a value of R2 0.9914 and a constant adsorption rate of 0.631 at an
adsorbate concentration of 10 ppm and a pH of 7 Cu metal solution.
