F. Kinetics Studies of Cu(II) Adsorption
The kinetics studies of Cu(II) adsorption were carried out by
batch adsorption at optimum conditions evaluated previously.
The samples were taken at preset time intervals up to 180
minutes under temperature of 30°C. The remaining
concentration of Cu(II) after adsorption was measured using
AAS and the amount of adsorption at time t, qt (mg/g) was
calculated by:
