摘要：

In the present investigation, chitosan and activated carbon are used as adsorbents for the removal of oxadiazon from aqueous solutions. The analyzing system was a gas chromatograph equipped with mass selective detector. The equilibrium studies are systematically carried out in a batch process, covering various process parameters that include agitation time, adsorbent dosage, and pH of the aqueous solution. Also, the relationship between extraction of oxadiazon and volume of aqueous/organic phase as well as the effect of inorganic salt were investigated. Adsorption behavior was found to follow Freundlich and Langmuir isotherms. The adsorption mechanism is described by a pseudo-second-order kinetics.
