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.
