Activated carbon/urea formaldehyde resin (AC/UF) may be used as a sorbent for textile dyes removal from industrial wastewaters such as methylene blue (MB). In order to obtain the adsorption mechanism of adsorption processes were studied by (FTIR) spectroscopy. The effect of various parameters like initial concentration, amount of AC composite doping, and mass dosage has been studied. Increasing the concentration of the adsorbent promoted an increase in the percentage of removal until saturation of the adsorbent. The experimental isotherm data were analyzed using Langmuir, Freundlich and Temkin models. Within the studied range of dye concentrations, the adsorption equilibrium was found to follow the Freundlich isotherm model well, with R2 > 0.985. The present adsorption studies of MB dye from aqueous solution revealed the potential of AC/UF to be utilized as an alternative, inexpensive, and environmentally benign adsorbent for water purification.
