Removal of Dyes from Waste Water Using Commercial Activated Carbon (CAC) as Adsorbent with Kinetic Aspect

الملخص

In this study, the removal of dyes which are present in the industrial wastewater
from Diwaniyaa textile factory, by commercial activated carbon (CAC) was
investigated as a function of temperature and pHs, residual amount of colored
wastewater determined using uv-visible technique at maximum wavelength 370 nm.
Adsorption process was attained to the equilibrium within 60 minutes, the
adsorbed amount of mixture dyes were found increased as temperature and pHs
decreased.
Kinetics of adsorption was studied by using Lagergreen’s equation at different
pHs and the adsorption rate constant Kad was calculated. The kinetic result indicates
that the adsorption process is pseudo first order. Activation energy was calculated
using Arrhenius equation which depends on the nature of the adsorbent surface.
