AB  - Three Ag(I)-organic frameworks, [Ag5(pydc)2(CN)]n, [Ag4(pydc)2]CH3CNn, and 
      [Ag(4,4'-bpy)NO3]n, were synthesized and embedded into silica gels to form 
      metal-organic-framework (MOF)-embedded gels for the microextraction of 
      polybrominated diphenyl ethers (PBDEs) in soils. Despite the great differences in 
      the structures of the organic ligands, all three Ag(I)-organic frameworks were 
      found to effectively accumulate and concentrate PBDEs from sample solutions 
      prepared with contaminated soil and purified water, indicating the important 
      roles of Ag centers in PBDE extraction. Under the optimal experimental conditions 
      (MOF mass, water volume, temperature, extraction time, and back-extraction time) 
      for PBDE extraction from sample solutions, the detection limits of seven PBDEs 
      (BDE-28, 47, 99, 100, 153, 154, and 183) ranged from 0.01 to 2.6ngg(-1) for 
      [Ag5(pydc)2(CN)]n, 0.20-0.64ngg(-1) for [Ag4(pydc)2]CH3CNn, and 
      0.60-3.08ngg(-1) for [Ag(4,4'-bpy)NO3]n. The reproducibilities of the three 
      methods were all satisfactory with relative standard deviations (RSDs) in the 
      range of 2.2-9.6%, 5.3-10.4%, and 6.9-9.4% for [Ag5(pydc)2(CN)]n, 
      [Ag4(pydc)2]CH3CNn, and [Ag(4,4'-bpy)NO3]n, respectively. The use of 
      Ag(I)-organic frameworks for the microextraction of PBDEs was validated using 
      both certified reference soils and field-contaminated soils, and the proposed 
      methods are recommended as rapid and environmentally friendly alternatives for 
      the extraction and determination of PBDEs in soils.
