The molecularly imprinted polymer was synthesized using atrazine as a template and methacrylic acid as a functional monomer. Assays performed in 25 mL of ultrapure water samples spiked at 8.0 \u03bcg\/L yielded 80\u2013120 % recoveries under the evaluated experimental conditions. The method showed an accuracy (0.2 &lt; bias &lt; 17.9%), precision (relative standard deviation &lt;17.4%), convenient detection (0.2 \u03bcg\/L), and quantification (0.7 \u03bcg\/L) limits, as well as linear dynamic ranges (0.8\u201324.0 \u03bcg\/L) with remarkable determination coefficients (<jats:italic>R<\/jats:italic><jats:sup>2<\/jats:sup> &gt; 0.9926). The proposed analytical method was applied to monitor triazines in three types of corn matrices using the standard addition methodology. Experiments performed in corn samples spiked with triazines at the trace level (8.0 \u03bcg\/kg of each analyte) gave rise to recoveries (81.0\u2013119.4%) with good reproducibility and robustness. The proposed methodology is also easy to implement and showed to be a good analytical alternative to monitor triazines in complex matrices, when compared with other sorption\u2010based microextraction techniques.<\/jats:p>","DOI":"10.1002\/jssc.201501101","type":"journal-article","created":{"date-parts":[[2015,12,3]],"date-time":"2015-12-03T04:28:38Z","timestamp":1449116918000},"page":"756-761","source":"Crossref","is-referenced-by-count":14,"title":["Determination of trace levels of triazines in corn matrices by bar adsorptive microextraction with a molecularly imprinted polymer"],"prefix":"10.1002","volume":"39","author":[{"given":"Felipe Nascimento","family":"Andrade","sequence":"first","affiliation":[{"name":"Institute of Chemistry of Sao Carlos, University of Sao Paulo  Sao Carlos SP Brazil"}]},{"given":"Alessandra Honjo","family":"Ide","sequence":"additional","affiliation":[{"name":"Centro de Qu\u00edmica e Bioqu\u00edmica, Faculdade de Ci\u00eancias Universidade de Lisboa  Campo Grande, Lisboa Portugal"}]},{"given":"Nuno da Rosa","family":"Neng","sequence":"additional","affiliation":[{"name":"Centro de Qu\u00edmica e Bioqu\u00edmica, Faculdade de Ci\u00eancias Universidade de Lisboa  Campo Grande, Lisboa Portugal"}]},{"given":"Fernando Mauro","family":"Lan\u00e7as","sequence":"additional","affiliation":[{"name":"Institute of Chemistry of Sao Carlos, University of Sao Paulo  Sao Carlos SP Brazil"}]},{"given":"Jos\u00e9 Manuel Flor\u00eancio","family":"Nogueira","sequence":"additional","affiliation":[{"name":"Centro de Qu\u00edmica e Bioqu\u00edmica, Faculdade de Ci\u00eancias Universidade de Lisboa  Campo Grande, Lisboa Portugal"}]}],"member":"311","published-online":{"date-parts":[[2016,2,22]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/jssc.201500070"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/jssc.201500039"},{"key":"e_1_2_8_4_1","first-page":"3766","volume":"38","author":"He Z.","year":"2015","journal-title":"Sci"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.chroma.2013.05.023"},{"key":"e_1_2_8_6_1","author":"Xi X.","year":"2015","journal-title":"J.
