摘要
The present work demonstrates that simultaneous determination of adrenalin （AD） and paracetamol （PAR） can be performed on single-walled carbon nanotube/chitosan/ionic liquid modified glassy carbon electrode （SWCNT-CHIT-IL/GCE）. The electro-oxidations of AD and PAR were investigated with cyclic voltammetry （CV）, differential pulse voltammetry （DPV） and also chronoamperometry （CA） methods. DPV experiments showed that the oxidation peak currents of AD and PAR are proportional to the corresponding concentrations over the 1-580 μmol/L and 0.5-400 μmol/L ranges, respectively. The RSD at a concentration level of 15 μmol/L AD and 15 μmol/L PAR were 1.69% and 1.82%, respectively. Finally the modified electrode was used for simultaneous determination of AD and PAR in real samples with satisfactory results.
