AB  - In this research, novel zirconia nanoparticles-decorated calcium alginate 
      hydrogel fibers (ZNCAHF) were synthesized through a simple, green procedure. 
      ZNCAHF were used as an adsorbent in the micro-solid-phase extraction (MSPE) of 
      methyl parathion (MP), fenitrothion (FT) and malathion (MT) as model pesticides 
      prior to gas chromatography-mass spectroscopic detection (GC-MS). The composition 
      and morphology of the prepared fiber were characterized by Fourier 
      transform-infrared spectroscopy (FTIR), field emission scanning electron 
      microscopy (FESEM), energy dispersive X-ray diffraction (EDX), and differential 
      scanning calorimetry (DSC). Various parameters affecting fabrication of the fiber 
      (weight ratio of components) and relative extraction recovery (pH, amount of 
      adsorbent, extraction time, salt addition, and desorption conditions) were 
      investigated and optimized. Under optimized conditions, the calibration curves 
      were obtained in the concentration range of 0.01-500ngmL(-1) with regression 
      coefficients between 0.9997 and 0.9999. The limits of detection (LOD) (S/N=3) and 
      limits of quantification (LOQ) (S/N=10) of the method ranged from 0.001 to 
      0.004ngmL(-1) and 0.003 to 0.012ngmL(-1), respectively. The intra-day and 
      inter-day relative standard deviations (RSDs) were 2.2-5.9% and 3.2-7.8%, 
      respectively. The applicability of the fabricated adsorbent was investigated by 
      extraction of selected organophosphorous pesticides (OPPs) from real samples of 
      juice and water. The obtained relative recoveries were in the range of 
      90.6-105.4%, demonstrating elimination of matrix effects which can be attributed 
      to the remarkable affinity of OPPs toward ZNCAHF.
