Application of Chitosan Film for the Removal of Triclosan from Aqueous Solutions by Adsorption

摘要

The aim of this work was to study the adsorption efficiency of chitosan as an adsorbent for triclosan, commercially known as Irgasan, in aqueous solutions. The effects of contact time, pH and temperature were investigated using a batch adsorption technique. Langmuir and Freundlich isotherms were used to analyze the equilibrium data at different absorption conditions. The results showed that the maximum adsorption capacity for chitosan was found in the acidic pH 3 and at a temperature of 65 °C. These results suggested that chitosan can be used as an adsorbent for removal of triclosan from aqueous solutions.
