The effects of various experimental parameters like mass of the <em>Typha australis</em> adsorbent and contact time have been investigated using a batch experiment. The adsorption kinetic data were analyzed using the Pseudo First Order (PFO) and Pseudo Second Order (PSO) models. The adsorption modeling was carried out using the Langmuir, Freundlich and Redlich-Peterson adsorption models. For kinetic study, the adsorption process fitted the PSO model and agreed with chemisorption. Both the Langmuir and Redlich–Peterson models were found to fit the adsorption isotherm data well, but the Redlich– Peterson model was better. The maximum adsorption capacity from the Langmuir model (q<sub>max</sub>) was 0.84 mg/g. The results of the present work showed that the <em>Typha australis</em> leaf, without any treatment has a good potential for iron removal from aqueous solutions via ultrasound-assisted adsorption. ultrasound-assisted adsorption Nonlinear Method kinetics Isotherms https://jpoll.ut.ac.ir/article_85957_fc1f3e7705d8b452d2e4e756523e4582.pdf
