Rapid Determination of Bisphenol A in Nursing Bottles by Flow Injection Inhibitory Chemiluminescence Analysis
摘要
Abstract
In order to establish a new rapid method for determining bisphenol A（BPA） in nursing bottles,cut pieces of nursing bottles were extracted with high-purity water under ultrasonic assistance,and the extracted analyte was enriched by solid phase extraction and determined using a uminol-H2O2-Cr chemiluminescence system.The esults showed that the chemiluminescence system was inhibited by BPA.An excellent linear relationship was observed in the range of 2.0 × 10-9-1.0 × 10-5 mol/L.The detection limit was 4.6 × 10-10 mol/L.The average spike recoveries of BPA in 5 types of commercial samples were in the range of 95.4%-106.8%,and the relative standard deviations for 7 parallel determinations were all less than 4%.The method had the advantages of sensitivity,simplicity,rapidity,low cost and accuracy over the Chinese national standard method,thus being worth promoting and popularizing.关键词
