AB  - In this work, a congo red modified single wall carbon nanotubes (CR-SWCNTs) 
      coated fused-silica capillary was prepared and used for capillary microextraction 
      (CME) of trace amounts of lanthanum (La), europium (Eu), dysprosium (Dy) and 
      yttrium (Y) in human hair followed by fluorinating assisted electrothermal 
      vaporization-inductively coupled plasma-optical emission spectrometry 
      (FETV-ICP-OES) determination. The adsorption properties and stability of the 
      prepared CR-SWCNTs coated capillary along with the various factors affecting the 
      separation/preconcentration of La, Eu, Dy and Y by CME were investigated in 
      detail. Under the optimized conditions, with a consumption of 2 mL sample 
      solution, a theoretical enrichment factor of 50 and a detection limit (3sigma) of 
      0.12 ng mL(-1) for La, 0.03 ng mL(-1) for Eu, 0.11 ng mL(-1) for Dy and 0.03 ng 
      mL(-1) for Y were obtained, respectively. The preparation reproducibility of the 
      CR-SWCNTs coated capillary was investigated and the relative standard deviations 
      (RSDs) were ranging from 4.1% (Eu) to 4.4% (La) (CLa, Dy=1.4 ng mL(-1); CY, 
      Eu=0.25 ng mL(-1), n=7) in one batch, and from 5.7% (Eu) to 6.1% (Y) (CLa, Dy=1.4 
      ng mL(-1); CY, Eu=0.25 ng mL(-1), n=5) among different batches. The proposed 
      method was applied to the analysis of real-world human hair sample and the 
      recoveries for the spiked sample were in the range of 93-105%. The method was 
      also applied to the determination of La, Eu, Dy and Y in Certified Reference 
      Material of GBW07601 human hair, and the determined values were in good agreement 
      with the certified values.
