Abstract

AbstractWater pollution causes health‐ and environment‐related problems. Adsorption of pollutants from the bulk is an efficient method for their removal. Modified biopolymers have proven to be effective adsorbents. The biopolymer gum ghatti (GG) has shown good adsorption properties. In this work, GG was grafted with polyacrylic acid (PAA) and loaded with oxidized multiwalled carbon nanotubes (O‐MWCNTs). The resulting GG‐g‐PAA/O‐MWCNT hydrogel was characterized by FT‐IR, XRD, and SEM and its adsorption activity was examined. Sodium diclofenac (SD) was efficiently removed by GG‐g‐PAA/O‐MWCNT. The highest removal efficiency of 92.89 % was achieved at pH 2. The adsorption of SD followed the Langmuir adsorption isotherm and pseudo‐second‐order model.
