Abstract

This study presents a method for the quantitative analysis of residual vinyl chloride monomer (VCM) in PVC products. In elution solvent, the extraction efficiency was similar by ethanol, THF, and acetone, but using n-hexane, it indicated relatively low extraction efficiency. Measuring VCM in the pulverized PVC samples, it showed reasonable results in both the direct injection method and headspace method with GC/MS. Regarding analysis of VCM in the intermediate sponge samples, five laboratories showed good results, and from the results, it was considered that VCM quantitative method in this study was reliable.

본 연구에서는 PVC 제품에 잔류하는 염화비닐 단량체(VCM)에 대한 정량분석방법을 제시하였다. 용출용매의 경우, 에탄올, THF, 아세톤에서 유사한 추출효율을 나타내었으나, 노말헥산을 이용한 경우에는 상대적으로 낮은 추출효율을 보였다. 분쇄 PVC 시료에 VCM 표준용액을 주입한 분석시료에 대한 VCM 함유량 측정 결과, GC/MS를 이용한 직접주입법이나 헤드스페이스법 모두 양호한 결과를 나타내었다. PVC 제품의 중간물질인 스펀지에서의 VCM 분석과 관련하여 5 개 시험전문기관의 시험소간 비교시험 결과, 각 시험소간 결과 편차가 크지 않은 것으로 나타나 본 연구에서 제시한 전처리 및 분석방법에 대한 플라스틱 제품내의 VCM 정량방법이 유효한 것으로 판단되었다.
