DETERMINATION OF BISPHENOL-A IN DRINKING WATER USING SPE SORBENTS WITH CHEMICALLY BONDED KETIOMINE GROUPS

In the paper, a new approach is described to determine the Bisphenol-A (BPA) in drinking water having contact with polycarbonate plastic. To determine the amount of BPA migrating from the plastic to the water, liquid-solid extraction was used connected with a gas chromatography (GC) analysis. In the presented work, a new SPE sorbent is proposed to determine Bisphenol-A contents. This sorbent contains chemically bonded ketoimine groups. This technique enabled detection limits of approximately 0.3 μg/L. A recovery of Bisphenol-A introduced into the water was also performed, locating recovery results in the range of 92.6%÷97.3%. The proposed method is simple and sensitive, thus highly suitable for the analysis of BPA in water. The new sorbent proposed is compared with popular C18 sorbent, to prove its usefulness in the chromatographic analysis.
