    Atrazine and 2, 4-D determination in corn samples using microwave assisted extraction and on-line solid-phase extraction coupled to liquid chromatography. por Santos Hernández, Ana Susana, Hinojosa Reyes, Laura, Sáenz Tavera, Isabel del Carmen, Hernández Ramírez, Aracely, Guzmán Mar, Jorge Luis

    Publicado 2018
    “…Prior to their analysis, microwave-assisted extraction approach for 2,4-D and atrazine in corn samples was carried out using MeOH: H2O (30:70 v/v) solvent at 50°C for 20 min. The on-line SPE-HPLC/UV approach combined reversed solid-phase extraction using Strata X sorbent with MeOH: H2O (80:20 v/v) at 1 mL min-1 as eluent for the enrichment of the analytes. …”
