Abstract
A simple and convenient digestion method was developed for the determination of heavy metal in polyurethane sample using only nitric acid in open system without heating. This digestion method had prevented loss of volatile elements of Hg and As and reduced the pretreatment time for the sample digestion. The detection limit is lowered over 10 times than that of microwave digestion method. Recoveries in polyurethane material were 108% for As, 96 ∼ 99% for Hg, 102 ∼ 103% for Cr, 98 ∼ 102% for Pb, 86 ∼ 90% for Cd, and 90 ∼ 93% for Cu
