Determination of Hg²⁺ in water samples with the proposed method.

Sample	Added (nM)	Measured (nM) a	Recovery (%)
tap water	2.0	2.1 ± 0.17	105 ± 0.085
	5.0	4.9 ± 0.32	98 ± 0.064
	10.0	9.6 ± 0.62	96 ± 0.062
river water	2.0	2.1 ± 0.11	105 ± 0.055
	5.0	5.1 ± 0.43	102 ± 0.086
	10.0	9.7 ± 0.65	97 ± 0.065

^a Mean values and standard deviations were obtained from three independent experiments.
