Adsorption of Acid Red by Porous Chitosan Film

Abstract:

The preparation, characterization, and environmental application of crosslinked porous chitosan films for Acid red (AR) adsorption have been investigated. The adsorbent was characterized by scanning electron microscope (SEM). The adsorption experiments were carried out in a batch system to optimize operation variables: contact time, Acid red concentration, temperature, and pH. The results indicated crosslinked porous chitosan films could successfully remove 96% of Acid red. The adsorption equilibrium isotherms showed that the sorption processes were better fitted by Langmuir equation.
