AB  - In this study, we synthesized an imidazolium ionic liquid immobilized on magnetic 
      mesoporous silica (IL-MMS) and evaluated its performance as a sorbent material 
      for a green micro-solid phase extraction (mu-SPE) of multiclass pesticides in 
      water. The synthesized IL-MMS was characterized by various analytical techniques, 
      including Fourier-transform infrared spectroscopy (FTIR), Brunauer-Emmett-Teller 
      (BET) and Barrett-Joyner-Halenda (BJH) analyses (N(2) adsorption/desorption), 
      Vibrating Sample Magnetometer (VSM), energy-dispersive spectroscopy (EDS) and 
      Field emission scanning electron microscopy (FESEM). Our synthesized IL-MMS 
      demonstrated excellent magnetic properties (31.5 emu/g), high surface area 
      (1177.4 m(2)/g), proper pore size (⁓4.2 nm) and volume (1.80 cm(3)/g). Under 
      optimized extraction conditions, the IL-MMS exhibited a high adsorption capacity 
      for a variety of pesticides, including organophosphates, carbamates, and 
      pyrethroids. The proposed mu-SPE method using IL-MMS showed good linearity 
      (R(2) > 0.99), low limits of detection (LODs) ranging from 0.04 to 1.63 ng/L, and 
      suitable recovery rate was between 82.4% and 109.8% for different pesticides. In 
      addition, the method also exhibited excellent reproducibility, with relative 
      standard deviations (RSDs) of less than 8% for both intra and inter-day 
      precision. In overall, the synthesized IL-MMS has proven to be a highly promising 
      material for sorbent-based micro-solid phase extraction (mu-SPE) of multiclass 
      pesticides in water. With its simple, efficient, and eco-friendly approach to 
      pesticide analysis, this method shows great potential for future pesticide 
      detection and monitoring efforts due to its sensitivity, accuracy, and 
      adaptability to various environmental conditions.
