Dan Lu,Yan-er Qian,

A new method for the determination of trace Sb in plastic pipes for drinking water was found. Cu is used as a matrix modifier in the transverse-orientation Zeeman background dedution GFAAS to determine trace Sb in plastic pipes for drinking water rapidly. The ashing temperature and atomization temperature were obtained by optimization process. The influences of medium acidity were studied. The best measurement conditions were selected. The sensitivity and precision of the method were improved. Sb was detected directly with a linear range of 0.27-20.0 microg x L(-1). The equation of working curve is Y = 0.0068X - 0.0002, r = 0.9996. The characteristic mass of the method is 6.7 pg. The detection limit is 5.4 pg. The recovery is 92.2%-102.5%. The RSDs were obtained from the data of 6 determinations at the concentration level of 5.0, 10.0 and 20.0 microg x L(-1) is 6.47%, 4.97% and 2.45% respectively. The method is simple, rapid, accurate and of highly sensitive and precise. Satisfactory results are obtained.
