Study on Adsorption Characteristics of Diamyl Phthalate by Sediment at Lanzhou Section of Yellow River

GUO Hong-Dong et al(Gansu Key Laboratory of Polymer Materials,College of Chemistry and Chemical Engineering,Northwest Normal University,Lanzhou,Gansu 730070)  
[Objective] The research aimed to master migration,transformation and fate of permanent organic toxin in middle and upper reaches of Yellow River better.[Method] Adsorption behavior of Diamyl phthalate(DAP) by sediment of Yellow River(Lanzhou section) was discussed by solid phase extraction, high performance liquid chromatography and UV spectrophotometry method.The effects of temperature,ionic strength,pH and organic matter content of sediment on adsorption were also discussed.[Result] The adsorption isotherms showed obvious S shape and the relativity fitted with Freundlich equation was better than that with Langmuir equation,which indicated that the adsorptive behavior could be contributed to multimolecular adsorption.The adsorption quantity was increased when temperature ascended and adsorption reaction was an endothermic process. The ionic strength,pH in water body environment,and organic matter content of sediment had certain effects on the adsorption of DAP.[Conclusion] This study provided definite theoretical foundation for migration,transformation and fate of permanent organic toxin in middle and upper reaches of Yellow River.
