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

Figure 2

Effect of varying the acceptor solvent on the extraction efficiency. Conditions: volume, 1 mL of 5 µg/mL atrazine and triclosan aqueous sample; 25 µL of a 1 : 4 (v/v) chlorobenzene : ethyl acetate mixture with the extraction time of 20 minutes.
