A method was developed for the simultaneous determining of five phenolic compounds,including biphenol A(BPA),octylphenol(OP),nonylphenol(NP),octyl phenoxypoly(ethyleneoxy)ethanol(OPEO) and nonylphenoxypoly(ethyleneoxy)ethanol(NPEO)) in waterborne coatings by QuEChERS/ultra high performance liquid chromatography with fluorescence detector(UPLC/FLD).Samples were dispersed firstly by QuEChERS(PSA+C18+MgSO4),and stirred uniformly to reduce the impurity,then extracted ultrasonically with dichloromethane-acetonitrile(1∶3).The ultimate solution was quantified by UPLC/FLD on a C18 column by gradient elution with water-acetonitrile as mobile phase at a flow rate of 0.2 mL/min.Under the optimized conditions,the method had good linear relationships(r>0.999 5) in the range of 5-1 300 μg/L for five compounds.The method detection limits(MLOD) for targeted compounds ranged from 0.4 mg/kg to 1.0 mg/kg.The spiked recoveries of five compounds varied from 97.5% to 114% with relative standard deviations(RSDs) of 2.6%-6.5%.The results showed that the method was simple,sensitive and precise,and could meet the qualification and quantification analysis requirements for BPA,OP,NP,OPEO and NPEO residues in waterborne coatings.
