The experiment was conducted with the SIM mode. The experimental results showed good linearity ranging from 1 to 50 μg/L, and the detection limits of 19 PBBs monomer were between 0.147 and 0.230 μg/L. The relative standard deviation was between 6.61% and 10.5%. Standard addition recovery was in the range of 61.5% to 82.6%. %R %U http://www.hjjkyyj.com/hjjkyyj/ch/reader/view_abstract.aspx %1 JIS Version 3.0.0
