dc.description.abstract마킹펜류는 어린이제품법의 안전확인으로 관리되는 학용품 품목으로서, 폼알데하이드 함유량에대한 안전기준은 20 mg/kg이다. 시중에 유통되는 마킹펜 9 종을 현행 시험법인 백포 필기 후 증류수 추출액을 UV/Vis 흡광광도계로 분석(이하 Nash-UV/Vis 방법)한 결과 폼알데하이드가 검출되지 않았고 수성 잉크와 같이 항시 추출액이 유색을 띠는 경우 거짓 양성 결과를 보였다. 반면, 잉크를 직접 초음파를이용하여 용해한 증류수 액을 DNPH 유도체화 한 후 HPLC/DAD로 분석(이하 DNPH-HPLC/DAD 방법)한결과, 최소 3.2 mg/kg ~최고 93.2 mg/kg이었고, 3종 제품이 안전기준 20 mg/kg을 초과하였다. 따라서, 추출과정이 빠르고 용이하도록 잉크를 직접 증류수에 용해한 후 DNPH-HPLC/DAD 분석 방법으로 잉크내 폼알데하이드 안전기준 20 mg/kg 이하 여부를 판단할 수 있도록 제안하고자 하며, 이 방법은 Nash- UV/Vis 방법의 검출한계 및 색상 물질 추출 시의 거짓 양성 결과의 한계를 극복할 수 있다. 형광펜, 보드마카, 물백묵, 페인트마카의 잉크 매트릭스를 사용하여 20 mg/kg 및 40 mg/kg의 범위에서 스파이킹 방법으로 산출한 DNPH-HPLC/DAD 분석방법의 정확도 및 정밀도는 각각 90.1 ~ 105.4% 및 0.6 ~ 3.3%이다. ;Marker pens belong to school things that are controlled by the regulation system called safety confirmation under special act on the safety of products for children with the formaldehyde criteria of 20 mg/kg. With nine marker pens available commercially, formaldehyde in marker pen ink was analyzed by present test standard where marking on a fabric swatch with a pen and extracting the swatch in water and derivatization with Nash reagent followed by UV/Vis spectrophotometeric measurement (Nash-UVNis method), giving not detected results or a false positive result in case of a colored water extract. However, the contents of formaldehyde in ink of nine marker pens were determinded to range between 3.2 similar to 93.2 mg/kg with three results above the safety criteria of 20 mg/kg by HPLC/DAD measurements on DNPH derivatives of formaldehyde (DNPH-HPLC/DAD method) in ink dissolved directly in water using an ultrasonic bath. Therefore, the DNPH-HPLC/DAD method with the extraction of ultrasonic dissolving ink in water is proposed as a proper method for analyzing formaldehyde in ink. The proposed method has advantages of lower detection limit and accuracy with colored extracts as well as a simple and fast extraction. The accuracy and precision of this method was estimated to be 90.1 similar to 105.4 % and 0.6 similar to 3.3 %, respectively by spiking tests in the ranges of 20 mg/kg and 40 mg/kg using matrixes such as highlighter pen ink, board marker ink, chalk marker pen ink and painter marker ink.-
