Kinetic and equilibrium study of trinitrophenol adsorption onto polyaniline tea waste nanocomposite from aqueous medium

The current study is focused on the synthesis of polyaniline-tea waste nanocomposite (PANI-TWC) material as a competent adsorbent for effective removal trinitrophenol (TNP) from aqueous medium. Batch experiments were performed to examine influence various adsorption parameters such pH, dose adsorbents, contact time and initial concentration TNP process. kinetic data fitted with pseudo-first pseudo-second-order models, studies well explained by model. Moreover, isotherm solutions PANI-TWC was Langmuir Freundlich models. equilibrium best isotherm, which indicated that surfaces are homogeneous occurred in monolayers.
