摘要：

The electrothermal atomization of lead has been investigated for accurate determination of lead in water samples. Thiourea served to lower the atomization temperature of lead and to eliminate the interferences from chloride matrix. The addition of thiourea also allowed the accurate determination of lead irrespective of its chemical form. The absolute sensitivity (1% absorption) was 1.1 × 10-12g of lead. The method permits the direct rapid determination of lead in water samples including sea water. © 1979 Springer-Verlag.
