چکیده انگلیسی
A novel sensor for the determination of parathion based on p-tert-butylcalix[6]-1,4-crown-4 as functional monomer was fabricated by sol-gel method using molecularly imprinted technology. The electrochemical behavior of parathion at the imprinted p-tert-butylcalix[6]arene-1,4-crown-4 sol-gel film sensor was characterized by cyclic voltammetry, linear sweep voltammetry, chronoamperometry and alternating current impedance spectroscopy. A fast response of parathion can be obtained after being incubated in 0.1Â M phosphonate buffer solution contain appropriate amount of parathion for 20Â min. A linear response over parathion concentration in the range of 5.0Â ÃÂ 10â9 to 1.0Â ÃÂ 10â4Â M was exhibited with a detection limit of 1.0Â ÃÂ 10â9Â M (S/NÂ =Â 3). This imprinted film sensor has been applied in determination of parathion in real sample and the results were consistent well with that obtained by high performance liquid chromatography.
