Abstract
The direct determination of lead in the whole-blood by graphite furnace atomic absorption spectrometric analysis was carried out by using the sample which was diluted five-fold with 1% Triton X-100. Matrix modification was tried to remove the interferences of blood matrix and also to get the optimum analytical condition. Good agreement with certificated values in reference materials(bovine blood) supplied by comparison program in Japan was obstained when 1%
본 연구에서는 흑연로 원자흡수분광법을 이용하여 혈액을 1% Triton X-100을 5배 희석시킨 다음 납 함량을 직접 측정하였다. 혈액내 방해 성분을 제거하기 위하여 매트릭스 변형제를 사용하여 최적의 분석 조건을 조사하였다. 매트릭스 변형제로서 1%
