Table 2. Determination of Cd²⁺ and Pb²⁺ in Commercial Mineral Water by Using the μCS.

	actual concentration (μg/L)^a		calibrated concentration (μg/L)^b
sample	[Cd²⁺]	[Pb²⁺]	[Cd²⁺]	[Pb²⁺]
mineral water	0	0	not detected	not detected
mineral water-10	10	10	10.8 ± 1.1	10.6 ± 1.4
mineral water-50	50	50	51.9 ± 2.9	50.3 ± 2.7

The concentration reached by adding Cd²⁺ and Pb²⁺ into the mineral water.

The concentration calculated based on the calibration plot shown in Figure 3b,d. At least three measurements were conducted to determine the standard deviation.
