Abstract

The determination method for the trace lead and cadmium in glass materials was developed by ICP-AES. The lead- and cadmium-DDTC chelates were formed by adding Na-DDTC (sodium diethyldithiocarbamate) as a chelating agent and extracted into MIBK (methyl-isobutyl ketone). Direct measuring of the trace lead and cadmium in glass was not possible because of the interferences of matrix elements as Na, Si, Mg and Ca of glasses unless solvent extraction of lead and cadmium was applied. This procedure was confirmed to be valid quantitative method of Pb and Cd analysis in glass did not influence of sample matrix, by applying it procedure to artifact sample and NIST SRM 1412.

유리소재 중의 미량의 납 및 카드뮴을 Na-DDTC를 가하여 Pb- 및 Cd-DDTC 착물을 형성시켜 유리 matrix 원소들로 부터 분리한 다음 MIBK로 추출하여 ICP-AES로 분석하였다. 유리 기질성분인 Na, Si, Mg 그리고 Ca 화합물 등은 미량의 납 및 카드뮴 정량에 방해작용을 하므로 직접 분석할 수 없으므로 용매추출법에 의해 Pb 및 Cd를 효율적으로 분리할 수 있었다. Pb 및 Cd 화합물이 첨가된 시험기준 시료와 NIST SRM 1412에 대한 용매추출실험에서 matrix의 영향을 받지 않고 정량하였다.
