The AuNPs were prepared by reducing chloroauric acid with sodium citrate. The effects of pyrolysis and atomization temperatures, the amounts of interferents and modifier on the sensitivities of arsenic and antimony were investigated. As and Sb remain in the graphite tube up to 1,100°C, which is sufficient for the determination of the two metals in certified reference materials and spiked sea water samples within a 95% confidence level with low RSD (<10%). The detection limits (N = 10 at 3σ) for As and Sb in sea water are 2.3μg L-1 and 3.0μg L-1, respectively. Almost no background as well as a blank value was detected for AuNPs.
