Abstract

Poly (ethylene naphthalate) (PEN), which is likely to be widely used in various application due to good barrier properties, is manufactured by condensation polymerization of 2,6-dimethylnaphthalene dicarboxylate (2,6-NDC) or 2,6-naphthalene dicarboxylic acid (2,6-NDA) with ethylene glycol. In this study, an analytical method to determine monomers in food simulants, which might migrate from PEN food contact materials into food, was developed. The HPLC-UV method was validated for 2,6-NDC and 2,6-NDA. The obtained validation parameters were selectivity, sensitivity, linearity, precision and recovery. The simultaneous HPLC method was considered the be most effective analytical method to determine 2,6-NDC and 2,6-NDA in food simulants.

연구에서는 PEN 수지 안전관리를 위하여 HPLC-UV 검출기를 이용한 2,6-NDC 및 2,6-NDA 분석법을 확립하였다. 분석법 검증 결과, 2,6-NDC 및 2,6-NDA 모두 $0.002{\mu}g/mL$ 검출한계, $0.005{\mu}g/mL$ 정량한계 및 $0.05{\sim}1{\mu}g/mL$의 농도 범위에서 $r^2$= 0.999 이상의 직선성을 확인할 수 있었다. 또한 회수율도 90~110%임을 확인할 수 있었다.
