Effects of Extracting Conditions on Anion Concentration in Soil

DONG Li-li,CHEN Yi-e(Department of Tourism and Resources,Environment,Xianyang Normal College,Xianyang 712000,China)  
Water-soluble chloride and sulfate ion concentration in moderate saline and alkaline soil collected from Zhongchuan Township of Minhe county in Qinghai province were measured.Effects of extracting conditions on Water-soluble chloride and sulfate ion concentration measured by ion chronmatography in soil were determined.The effects of extracting time and water-soil ration on results were analyzed.Results showed: the water-soil ration was 20 ∶1,chloride and sulfate ion content were highest at extracting 60 min,while water-soil ration was 10 ∶1,chloride and sulfate ion content were highest at extracting 30 min.
