Rapid determination of tetrabromobisphenol A and its main derivatives in aqueous samples by ultrasound-dispersive liquid–liquid microextraction combined with high-performance liquid chromatography

Silver ion post-column derivatization electrospray ionization mass spectrometry for determination of tetrabromobisphenol A derivatives in water samples

“…21,22,38 Hyphenated HPLC with mass spectrometry (MS) employed different ionization sources, such as electrospray ionization (ESI), 18,39 atmospheric pressure chemical ionization (APCI) 20 and atmospheric pressure photoionization (APPI), 13 could determine only certain types of TBBPA derivatives. For example, ESI was able to ionize only the byproducts of TBBPA derivatives, but failed to ionize the main products because of their low proton affinities.…”

“…18,[20][21][22] Aer HPLC separation, the derivatives were reacted with 10 mg L À1 of Ag + sequentially to form complexes of Ag + and TBBPA derivatives. Then, the complexes were electrosprayed and detected by ESI-MS.…”

Recent advances in the analysis of TBBPA/TBBPS, TBBPA/TBBPS derivatives and their transformation products

“…Wang et al reported an in situ synthesized capillary poly monolith as the SPME medium for simultaneous extraction of three BFRs, including TBBPA [35]. Some novel solid phases, including mesoporous cellular foams (MCFs), mesoporous silica materials, and phenyl-modified mesoporous materials, were synthesized and used as fiber coating materials for SPME [36]. By using a stainless steel wire as a supporting core, fibers were prepared with a sol-gel method and immobilized for extraction of TBBPA/S and TBBPA/S derivatives.…”

“…By using this method, TBBPA and its five derivatives could be extracted using ultrasound-DLLME, which provided recoveries of about 80-100% for tap water, river water, or chemical wastewater, and 45-120% for urine or fruit juice samples [36].…”

Ultrasound-assisted extraction of emerging contaminants from environmental samples

“…UA-DLLME has been applied in water samples to analyze different FRs: polybrominated diphenylethers (PBDEs) [15], tetrabromobisphenol A (TBBPA) and its five derivatives [16], and Dechlorane together with other chlorinated FRs [17]. The sonication time is a crucial variable in this procedure; a prolonged time may induce the loss of analytes by volatilization due to the high dispersion of droplets in aqueous phase.…”
