Table 4

Comparison of the presented method with other reported methods for iodate determination.

Detection system	LOD (μg mL^−1)	Linear range (μg mL^−1)	RSD (%)	Reference
FI-UV-Vis	0.02	0.1−30	1.2	[4]
Reverse FI-UV-Vis	0.008	0.2−3	0.9	[8]
Sequential FI-UV-Vis	0.05	0.05−10	0.8	[9]
TICP-CZE-UV	0.0035	Up to 5	1.08	[21]
LPME-microvolume UV-Vis	0.001	0.0075–0.175	4.2	[27]
SPE-spectrophotometry	0.12	0.2–2.8	2.5	This work

Notes: LOD: limit of detection; RSD: relative standard deviation; LPME: liquid-phase microextraction; FI: flow injection; TICP-CZE-UV: transient isotachophoresis-capillary zone electrophoresis with UV detection.
