Single-Walled-Carbon-Nanotube-Modified Pyrolytic Graphite Electrode Used as a Simple Sensor for the Determination of Salbutamol in Urine

Table 2

Recovery data for salbutamol determination in plasma samples of healthy volunteers at SWNT-modified EPPGE.

Spiked amount (μM)	Detected amount^a (μM)	Recovery (%)
Sample 1
0.50	0.50	100.00
1.00	0.99	99.00
1.50	1.49	99.33
Sample 2
0.50	0.49	98.00
1.00	0.98	98.00
1.50	1.49	99.33

^aThe RSD value for the determination of salbutamol was less than ±3.2% for 𝑛=3.
