In this study, a porous organic polymer (denoted as Car-DMB) was fabricated by a simple one-step crosslinking polymerization of carbazole and p-dimethoxybenzene for the first time. Then the Car-DMB was served as adsorbent of solid phase extraction to enrich triazine herbicides from white gourd, tomato and soybean milk samples prior to their determination by high performance liquid chromatography. Under the optimal conditions, the response linearity was in the range of 0.3-100.0 ng g(-1) for white gourds and tomato samples, and 0.5-100.0 ng mL(-1) for soybean milk, with the coefficient of determination higher than 0.996. The detection limits were 0.1-0.2 ng g(-1) for white gourd and tomato samples, and 0.15-0.3 ng mL(-1) for soybean milk. The adsorption mechanism of the Car-DMB for the triazines was attributed to the strong H-bonding and weak p-p interactions. The efficient extraction for several other compounds demonstrated that Car-DMB holds great potential for diverse analysis applications.
