Adsorption kinetics for tartrazine on chitosan have been done at optimum pH to determine the kinetically dimensions, to compare the linear and non-linear methods and to predict a mechanism of adsorption. The chitosan which used is the product of chemical deacetylation from commercial chitin. Tartrazine can be adsorbed on chitosan at an optimum pH of 9.0. At this pH, the adsorption systems followed the nonlinear method of pseudofirst-order kinetics model with the adsorption rate constant of 0.01821/ min and the adsorption capacity of 2.682 mg/g. The adsorption mechanism that occurred in this process was studied using the diffusion film from the beginning until the equilibrium was reached.
