Abstract

A novel and sensitive method was proposed for determination of tramadol and diltiazem concentrations in water using capillary electrophoresis coupled with electrochemiluminescence. The effects of experimental conditions were investigated. Under optimized conditions, the calibration plot was linear over tramadol concentrations in the range 6 × 10-6 to 3 × 10-4 mol/L (r ³ 0.997), with a detection limit (S/N = 3) of 3.012 × 10-8 mol/L, diltiazem concentrations in the range 5 × 10-7 to 2 × 10-4 mol/L (r ³ 0.986), with a detection limit of 1.038 × 10-8 mol/L (S/N = 3). For the determination of tramadol and diltiazem concentrations in waterbodies, the relative standard deviation (RSD) of electrochemiluminescence intensity and migration time were and 4.55 % to 4.58 %, 1.73 % to 2.01 %, 0.72 % to 1.39 % and 0.97 % and 1.11 %, respectively. The proposed method was simple, rapid, sensitive and also had the merits of good reproducibility without external interference, on small samples. It was applied to determine tramadol and diltiazem concentrations in lake water samples which showed higher recoveries thereof. The new set-up was able to detect a matrix of samples both directly and simultaneously.
