Hollow-Fibre-Supported Dispersive Liquid-Liquid Microextraction for Determination of Atrazine and Triclosan in Aqueous Samples

Table 1

Some analytical data obtained from the regression analysis.

Analytical data	Atrazine	Triclosan
Coefficient of determination,	0.9975	0.9977
Estimated LOD (μg mL^−1)	0.0081	0.0169
Enrichment factor, EF	127	142
Amount in river water sample	n.d. (98)	n.d. (101)
Amount in sewage water	n.d. (97)	n.d. (96)
Reproducibility (%RSD, )	6.9	7.6

Limit of detection, LOD, calculated from the equation LOD = ; EF = . The values in parenthesis demonstrate the percentage recovery of the spiked samples.
