Tóm tắt

A novel method for the separation/analysis of linuron in fruit and vegetable samples is described. The work is based on the utilization of ionic liquid ([C6min][PF6])-loaded β-cyclodextrin cross-linked polymer (IL-β-CDCP) for the effective adsorption of linuron coupled with ultraviolet spectrophotometry. The inclusion interaction of IL-β-CDCP with linuron is studied with FTIR and inclusion constants. Under optimum conditions, the preconcentration factor achieved for this method is approximately 10. Linear range, limit of detection (LOD), limit of quantification (LOQ), and relative standard deviation are 0.08–15.00 μg/mL, 5.8 ng/mL, 17.5 ng/mL and 0.96 % (n = 3, c = 4.0 μg/mL), respectively. This technique is successfully applied for determination of linuron in real samples.
