چکیده
|
A stable and sensitive electrochemiluminescence (ecl) detection protocol of o-aminophenol was developed,which was based on cdse quantum dots (qds) and the cavity structure of β-cyclodextrin. in this experiment,the working electrode was prepared by pamam and cdse qd and β-cyclodextrin using layer self-assembly method under the infrared lamp. under the optimum conditions,a good linear relationship with the concentration of o-aminophenol from 1.0 × 10 -7 mol l-1 to 8.0 × 10 -6 mol l-1 and the detection limits as low as 2.3 × 10 -8 mol l-1 (3σ) were achieved. good selectivity and repeatability are advantages of the sensor which is feasible.
