초록

플라스틱 시료 중 각종 유해물질 유무 확인을 위한 여러 가지 시험항목을 저비용으로 빠르게 분석할 수 있는 방법으로 Combustion ion chromatography(연소IC)를 사용한 방법을 채택하였다. F, Cl 및 Br의 3개 항목에 대하여 연소IC로 시험법 유효화 검증을 실시한 결과, 검량선은 0.5~4.0 mg/kg 농도범위에서 $r^2$ = 0.999~1.000의 상관관계 계수를 갖는 좋은 직선성을 나타내었으며, 검출한계는 0.005~0.024 mg/kg, 정량한계는 0.014~0.073 mg/kg 이였다. 인증표준물질(CRM)을 사용한 연소IC의 회수율은 95.5~104.9%이었다. 본 결과를 토대로 국내외 시험기관간 비교 숙련도 시험을 실시하였으며, 그 결과 연소IC 방법이 전기전자제품 중에 halogen-free 및 기타 유해물질 규제 대응을 위한 효율적인 분석방법임을 확인하였다.

For plastics samples, a method using combustion ion chromatography was selected as a method for rapid low-cost analysis to test whether hazardous substances are contained or not. Using combustion ion chromatography, a verification test for F, Cl and Br compounds generated a linear calibration curve with a correlation coefficient of $r^2$ = 0.999~1.000 in the calibration range from 0.5 to 4.0 mg/kg. The detection limits were found to be 0.005~0.024 mg/kg and quantitative limits were found to be 0.014~0.073 mg/kg. The recoveries of combustion ion chromatography using certified reference material (CRM) were found to be 95.5~104.9%. Based on these results, a proficiency test was conducted together with several laboratories in and out of the country, to make comparative analysis of the results from each laboratory. As a result, the data supported the use of combustion ion chromatography as an effective analysis method to deal with regulations for halogen-free electronic products and for other hazardous substances in the electronic products.
