ABSTRACT
In this paper, a novel magnetic hyper-crosslinked polymer with amino and triazine bifunctional groups (M-NH2-THCP) was developed. M-NH2-THCP has strong nitroimidazoles (NDZs) enrichment effect, and therefore it was used as an adsorbent to extract five NDZs from lake water, catfish and shrimp meat prior to HPLC. Polar interaction, π-π stacking interaction, hydrogen bond and Lewis acid-base interaction were attested to be the major adsorption mechanism. The method has a good linearity in the range of 0.1-100 ng mL-1 for lake water, 10-400 ng g-1 for catfish and shrimp muscle with R2 > 0.9964. The limits of detection of NDZs were 0.03-0.04 ng mL-1 for lake water, 1.0-2.0 ng g-1 for catfish and 2.0-2.5 ng g-1 for shrimp, which is superior to most reported method. The method recoveries were 87.6-119 %, and relative standard deviations were less than 8.7 %. M-NH2-THCP holds great application potential in pollutants enrichment, separation and removal.
