Rapid detection of ultratrace pollutants in complex matrixes is a great challenge for studying their environmental behaviors and impacts. A method is developed by combining covalent organic framework (COF) based solid phase microextraction (SPME) with constant flow desorption ionization mass spectrometry for rapid detection of trace tetrabromobisphenol A (TBBPA) in multiple water media. The limits of detection and qualification are 0.92 and 3.1 ng L-1 for TBBPA, resp. The linear range is 0.01-10 μg L-1 (R2 = 0.9992), and the relative standard deviations with single fiber and multiple fibers are 6.4% and 6.7% (0.1 μg L-1, n = 9), resp. The detection of nanogram per L levels of TBBPA in tap water, river water, seawater, and beverage can be achieved in 7 min. In the experiment, the researchers used many compounds, for example, 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4COA of Formula: C9H6O6)
2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4) is a member of phloroglucinol derivatives. Phloroglucinol derivatives are a major class of secondary metabolites. Phloroglucinol compounds can be classified into monomeric, dimeric, trimeric and higher phloroglucinols, and phlorotannins.COA of Formula: C9H6O6
