A resin of 2-aminophenol-formaldehyde (2-A-Ph-F) was prepared and characterized by FT-IR technique. This resin was loaded on polystyrene (PS) as a matrices using DMF solvent, after that the polymer solution was used in electrospinning process in order to result electrospun nanofiber mat (2-A-Ph-F)/PS which has been used as adsorbent surface for studying the adsorption kinetic of malachite green dye (MG) at different temperatures to observe the behavior of this adsorption system. Generally, there is an increase in the values of rate constants with increasing temperature and the experimental results obeyed very well Lagergren's equation. So, the activation energy value (Ea) was estimated by Arrhenius equation, while the diffusion mechanism and the rate controlling steps explained according to Weber's intraparticle diffusion model.
