AB  - A magnetic starch modified with 3,5-diaminobenzoic acid and 
      3-aminopropyltriethoxysilane (Fe-starch@DABA-APTES) was synthesized and applied 
      as adsorbent for the extraction of organochlorine pesticides (OCPs). Magnetic 
      solid-phase extraction was developed using 75 mg of the sorbent and 15 mL of a 
      sample solution. Extraction was conducted on a vortex mixer for 40 s. The 
      adsorbent was collected using an external magnet before eluting the analytes 
      using 0.5 mL of methanol. Quantification of the analytes was performed using gas 
      chromatography with a micro-electron capture detector. The linearity was obtained 
      for the studied OCPs in the range between 0.01 - 2.00 mug L(-1). The detection and 
      quantification limits were obtained in ranges of 0.5 - 4.0 and 
      1.5 - 15.0 ng L(-1), respectively, with enrichment factors of up to 39. The 
      precision in terms of the intra- and inter-day relative standard deviations 
      (RSDs) were below 4.75, and 9.25%, respectively. The developed method has been 
      applied in natural water and agricultural product samples. The recoveries ranged 
      between 59.83 - 132.67% (RSDs < 10.73%).
