N2  -  Due to their high polarity andsolubility in water these acidic herbicides can be released from harvest fields and therefore pollute surface and ground waters. The World Health Organization (WHO) regulations set 70 ng mL−1 as the maximum contaminant level (MCL) of phenoxy acid herbicidesin drinking water [2]. Therefore, the presence of these chemicals inwater sources is highly objectionable for human and animal consumption. Due to the fact that the major sources of drinking water are ground water and river water, monitoring the acidic and polar herbicides in these water sources is quite necessary. Therefore, in this study, we focused on introducing a novel microgel sorbent in which the adsorption and desorption of analytes are controlled only by changing the pH value of the sample. To the best of our knowledge, it is the first report on employing a pH-sensitive magnetic microgel as a new sorbent. In order to increase the adsorption efficiency and rapidly separatethe sorbent from the sample matrix by an external magnetic field, microgel was grafted on magnetic nanoparticles. Finally, the optimized procedure was employed to determine these phenoxy acid herbicides in river water samples.
