초록

역상 HPLC를 이용하여 식품용 캔에서 이행된 캔 식품 및 식품 유사용매 중에 잔류하는 BADGE, BFDGE 및 가수분해 또는 염화물(chlorinated) 형태인 그들의 분해산물인 $BADGE{\cdot}H_2O$, $BADGE{\cdot}2H_2O$, $BFDGE{\cdot}H_2O$, $BFDGE{\cdot}2H_2O$, $BADGE{\cdot}HCl{\cdot}H_2O$, $BADGE{\cdot}HCI$, $BADGE{\cdot}2HCl$, $BFDGE{\cdot}HCl{\cdot}H_2O$, $BFDGE{\cdot}HCl$$BFDGE{\cdot}2HCI$ 또는 BADGE와 BFDGE의 합성에 사용되는 출발물질인 BPA 및 BPF를 정량하고 이들 물질을 $MSTFA-NH_4I-DTE$ 유도체화 시약으로 유도체화 시킨 뒤 GC/MSD로 정성하는 동시분석법을 확립하였다. 이 방법은 캔 식품 및 식품 유사용매에 각 100 ng/mL의 BPA, BPF, BADGE 및 BFDGE를 첨가하여 행한 회수율 시험에서 $4.1{\sim}7.0%$의 상대 표준편차를 갖는 $90{\sim}114%$의 회수율을 보여 주었으며 검출한계가 $6{\sim}11ng/mL$이었고 정량한계는 $12{\sim}18\;ng/mL$이었으며 검량선의 상관계수도 0.9987이상의 우수한 직선성을 보여 주었다. 따라서 본연구의 방법은 식품용 캔에서 이행된 캔 식품 및 식품 유사용매 중에 잔류하는 BPA, BPF, BADGE, BFDGE 및 가수분해 또는 염화물형태인 그들의 분해산물을 정량함에 있어 적합한 방법이 될 수 있음을 확인할 수 있었다.
