Remediation of noxious chromium (VI) utilizing acrylic acid grafted lignocellulosic adsorbent

► Acrylic acid modified Ficus carica lignocellulosic fiber was used as adsorbent. ► The adsorbent was characterized using instrumental techniques. ► The adsorption data was studied for isotherms, kinetic models and thermodynamics. ► The removal of Cr(VI) was evaluated in the presence of various metal ions. ► The desorption experiment showed that 35.74% of metal ions was recovered.
