      Solid-Phase Extraction of 11 Triazole Fungicides in Fruit Samples.

AB  - Carbon-based Fe(3)O(4) nanocomposites (C/Fe(3)O(4) NCs) were synthesized by a simple 
      one-step hydrothermal method using waste pomelo peels as the carbon precursors. 
      The characterization results showed that they had good structures and 
      physicochemical properties. The prepared C/Fe(3)O(4) NCs could be applied as 
      excellent and recyclable adsorbents for magnetic solid phase extraction (MSPE) of 
      11 triazole fungicides in fruit samples. In the MSPE procedure, several 
      parameters including the amount of adsorbents, extraction time, the type and 
      volume of desorption solvent, and desorption time were optimized in detail. Under 
      the optimized conditions, the good linearity (R(2) > 0.9916), the limits of 
      detection (LOD), and quantification (LOQ) were obtained in the range of 1(-)100, 
      0.12(-)0.55, and 0.39(-)1.85 μg/kg for 11 pesticides, respectively. Lastly, the 
      proposed MSPE method was successfully applied to analyze triazole fungicides in 
      real apple, pear, orange, peach, and banana samples with recoveries in the range 
      of 82.1% to 109.9% and relative standard deviations (RSDs) below 8.4%. Therefore, 
      the C/Fe(3)O(4) NCs based MSPE method has a great potential for isolating and 
      pre-concentrating trace levels of triazole fungicides in fruits.
