AB  - An effective method for the preparation of magnetic molecularly imprinted 
      polymers (MIPs) on attapulgite (ATP) using microcystin-LR (MC-LR) as template 
      molecule through reversible addition fragmentation chain transfer (RAFT) radical 
      polymerization was reported. A novel MIPs stir bar sorptive extraction (SBSE) 
      coating was prepared by sol-gel method. The structure and morphology of MIPs were 
      characterized by infrared spectroscopy (IR) and transmission electron microscopy 
      (TEM). The adsorption performance of SBSE coated with MC-LR was studied by high 
      performance liquid chromatography (HPLC). The results showed that under the 
      optimized experimental conditions, the present method has high selectivity to 
      MC-LR. A good linearity was achieved for MC-LR over the range of 0.010-5.0 mg/L 
      and the limit of detection (S/N = 3) was found to be as low as 0.27 mug/L. The 
      proposed method was successfully applied to the determination of MC-LR in water 
      samples. The average recoveries ranged from 83.33% to 100.07% with the relative 
      standard deviations (RSDs) of 1.40%-9.17% at three spiked levels (20, 40 and 80 
      mug/L). The developed method is rapid, selective and sensitive, and adapts to the 
      analysis of trace MC in water samples.
