• Chitosan nanoparticles extracted from shrimp shells, application for removal of Fe(II) and Mn(II) from aqueous phases (2018, background): “Chitosan has the ability to adsorb significant amounts of metal ions over a wide range.([4,8]) Chitosan is a polysaccharide which is made from the chitin present in the exoskeletons of the various crustaceans.”
• Removal of arsenic, methylene blue, and phosphate by biochar/AlOOH nanocomposite (2013, methodology): “While the Elovich model is an empirical equation considering the contribution of desorption, the first-order and second-order models are semimechanistic models based on the mononuclear and binuclear adsorption mechanisms, respectively [29].”
