| Abstract In this study, the removal of dyes which are present in the industrial waste-water 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 | ||
