Abstract
Detection and removal of iron are of great interest to environmental chemists. Herein, activated carbon has been synthesized from saw dust. Tin oxide nanoparticles were loaded on activated carbon to prepare efficient nanoadsorbent for the removal of iron from water. The prepared adsorbent was investigated and characterized by various techniques, such as FTIR, SEM, XRD, EDX analysis.

The removal of iron was monitored by considering various parameters like amount of adsorbent, contact time and concentration of iron. Kinetic studies showed best fitting of pseudo first order kinetics with rate constant 0.012 min-1. The adsorption process was analyzed by using Freundlich isotherm and Langmuir isotherm models.
