Table 2

Analytical characteristics of proposed method.

Parameter	Analytical feature
Linear range (μg L^−1)	0.05–1.0
Limit of detection (μg L^−1) (𝑛=10)	0.02
Repeatability (RSD^a, %) (𝑛=10)	3.5
Enrichment factor^b	166.5

aPd(II) concentration was 0.2 𝜇g L⁻¹ for which RSD was obtained.
bConcentration factor is the volume ratio (V_a/V_s) of the aqueous phase (V_a) and volume of sedimented phase (V_s).
