AB  - A novel porous coordination polymer adsorbent (BTCA-P-Cu-CP) based on a 
      piperazine(P) as a ligand and 1,2,4,5-benzenetetracarboxylic acid (BTCA) as a 
      linker was synthesized and magnetized to form magnetic porous coordination 
      polymer (BTCA-P-Cu-MCP). Fourier transform infrared (FTIR), X-ray diffraction 
      (XRD), vibrating sample magnetometer (VSM), field emission scanning electron 
      microscope(FESEM), energy-dispersive X-ray spectroscopy(EDS), CHN, and 
      Brunauer-Emmett-Teller(BET) analysis were used to characterize the synthesized 
      adsorbent. BTCA-P-Cu-MCP was used for removal and preconcentration of Pb(II) ions 
      from environmental water samples prior to flame atomic absorption 
      spectrometry(FAAS) analysis. The maximum adsorption capacity of BTCA-P-Cu-MCP was 
      582 mg g(-1). Adsorption isotherm, kinetic, and thermodynamic parameters were 
      investigated for Pb(II) ions adsorption. Magnetic solid phase extraction (MSPE) 
      method was used for preconcentration of Pb(II) ions and the parameters 
      influencing the preconcentration process have been examined. The linearity range 
      of proposed method was 0.1-100 mug L(-1) with a preconcentration factor of 100. 
      The limits of detection and limits of quantification for lead were 0.03 mug L(-1) 
      and 0.11 mug L(-1), respectively. The intra-day (n = 7) and inter-day (n = 3) 
      relative standard deviations (RSDs) were 1.54 and 3.43% respectively. The 
      recoveries from 94.75 +/- 4 to 100.93 +/- 1.9% were obtained for rapid extraction of 
      trace levels of Pb(II) ions in different water samples. The results showed that 
      the BTCA-P-Cu-MCP was steady and effective adsorbent for the decontamination and 
      preconcentration of lead ions from the aqueous environment.
