AB  - Herein, a composite of polyacrylonitrile (PAN)/agar/silver nanoparticles (AgNPs) 
      electrospun nanofibers was fabricated and applied as an efficient sorbent for 
      thin-film micro-extraction (TFME) of five metal ions followed by inductively 
      coupled plasma optical emission spectroscopy (ICP-OES). Incorporating agar into 
      the nanofibers followed by in situ photo-reductive reaction under UV-lamp 
      resulted in highly uniform dispersion of AgNPs in the nanofibers. Under the 
      optimized conditions, agreeable linearity was acquired in the range of 
      0.5-250.0 ng mL(-1) (R(2) >/= 0.9985). The LODs (based on S/N = 3) were attained in 
      the range of 0.2 to 0.5 ng mL(-1). The relative standard deviations (RSDs) were 
      between 4.5% and 5.6% (intra-day, n = 5) and 5.3%-5.9% (inter-day, n = 3) for 
      three sequential days. The developed method was investigated with water and rice 
      samples, and recoveries (93.9-98.0%) indicated that the PAN/agar/AgNPs could be a 
      promising film for the adsorption of heavy metal ions in varied samples.
