The production of dye is increased rapidly due to the development of various
industries. The removal of dye could be carried out by using activated carbon through
adsorption process. Currently, several types of agricultural wastes and fruits were used to
produce activated carbon. In this work, removal of Congo red, crystal violet, turquoise blue,
reactive black 5, and malachite green onto activated carbon was studied. The adsorption and
equilibrium data were investigated using different models. Experiment results show that
adsorption process is endothermic and spontaneous process.
