Flow-Injection Preconcentration of Chloramphenicol Using Molecularly Imprinted Polymer for HPLC Determination in Environmental Samples
Figure 6
Chromatograms recorded in HPLC system with UV detection for eluates from preconcentration 100 mL samples in MIP flow through reactor, and elution with 1 mL methanol. Prior to the injection eluates diluted 3 : 2 with water, and injected 20 μL. (a) 1: tap water, 2: tap water spiked with 1 μg/L CAP. (b) 1: 1 μg/L standard solution of CAP, 2: river water, 3: river water spiked with 1 μg/L CAP. Preconcentration carried out with flow rate 1.92 mL/min, elution with flow rate 0.36 mL/min. Asterisk indicates CAP peak.
