垃圾渗滤液中所含的有机污染物成分复杂、浓度高.在采用GC-MS法对其初步定性时预处理方式对检测结果影响较大,考察了液液萃取、固相萃取、大孔树脂吸附三种常见预处理方式对检测结果的影响,固相萃取适于测定垃圾渗滤液中醇酚类为主的物质;而大孔树脂对芳烃类与酯类的富集效果最佳;液液萃取对烯烃类及羧酸类物质萃取效率较高.采用固相萃取测得渗滤液中含有62种物质,其中EPA优先控制污染物有3种.
垃圾滲濾液中所含的有機汙染物成分複雜、濃度高.在採用GC-MS法對其初步定性時預處理方式對檢測結果影響較大,攷察瞭液液萃取、固相萃取、大孔樹脂吸附三種常見預處理方式對檢測結果的影響,固相萃取適于測定垃圾滲濾液中醇酚類為主的物質;而大孔樹脂對芳烴類與酯類的富集效果最佳;液液萃取對烯烴類及羧痠類物質萃取效率較高.採用固相萃取測得滲濾液中含有62種物質,其中EPA優先控製汙染物有3種.

The landfill leachate contains organic pollutants with complicated components and high concentration.The determination results are significantly influenced when a qualitative test of landfill leachate is performed by GC-MS.The influence of three common pretreatment methods including liquidliquid extraction,solid phase extraction,macroporous resin adsorption on the test results was investigated.The solid phase extraction is suitable for testing alcohols and phenols in landfill leachate.The macroporous resin has the best enrichment efficiency of aromatic hydrocarbons and esters.The liquid-liquid extraction is more efficient in extraction of alkenes and carboxylic acids.Sixty-two organic pollutants in landfill leachate were determined by solid phase extraction,including three priority control pollutants.
