The green composite chitosan/tripolyphosphate/mushroom (C‐TPP‐PEE) was synthesized and evaluated for its adsorption performance of the dye Reactive Orange 16 (RO16), by using the batch technique. Fourier‐transform infrared spectroscopy, thermogravimetric analysis, and field emission scanning electron microscopy were employed to characterize the C‐TPP‐PEE. The maximum adsorption capacity of the RO16 dye for batch adsorption was determined as 736 mg g −1 . The experimental kinetic data at equilibrium was found to be best fitted to the pseudo‐second‐order kinetic model. The results showed that the adsorption isotherm was best correlated to the Langmuir model. The thermodynamic data indicated that the adsorption process was spontaneous, favorable, and endothermic.
