Table 3

Parameters of calibration regression straight lines and limits of detection (LOD) and quantification (LOQ) of rutin on the tested carbon paste electrodes, DPV measurement.

Electrode	c (μmol L^−1)	Regression equation y = ax + b	R	LOD (mol L^−1)	LOQ (mol L^−1)
CPE	0.2–8	y = 2 × 10^8x −41.90	0.9911	2 × 10^−7	7 × 10^−7
IL/CPE	0.6–6	y = 3 × 10^8x + 41.89	0.9944	6 × 10^−7	2 × 10^−6
IP/CPE	0.08–6	y = 2 × 10^8x −9.64	0.9955	8 × 10^−8	3 × 10^−7

c: linear concentration range, R: correlation coefficient.
