Abstract

The acid digestion bomb pretreatment method for the determination of antimony in a commercial fire retardant material sample (DBDPE-$Sb_2O_3$) was studied. DBDPE-$Sb_2O_3$ sample was digested with $H_2SO_4:HCl$(1:2) mixture in digestion bomb at $220^{\circ}C$ for 2 hrs. and antimony was determined by atomic absorption spectrophotometry. Recovery of 99.6-99.8% and C.V. of 0.94-1.07% for Sb was obtained for spiked real samples. In the present method, the analytical results obtained for antimony were 40.3 and 36.3% (w/w), respectively.

상용되는 난연제인 DBDPE-$Sb_2O_3$ 중 안티몬을 신속 정확하게 분석하기 위하여 가압 산 분해법을 이용하여 전처리하였다. DBDPE-$Sb_2O_3$ 시료를 가압 산 분해장치 내에서 $H_2SO_4:HCl$(1:2) 혼합산을 가하여 $220^{\circ}C$에서 2시간 동안 분해시킨 후 AAS를 이용하여 Sb를 정량하였다. 그 결과 99.6-99.8%의 회수율과 0.94-1.07%의 변동계수값을 얻었다. 이 전처리 방법을 실제시료에 적용하여 40.3과 36.3%의 Sb 함량을 구할 수 있었다.
