摘要

The determination of Ag, Bi, Cd, Zn, and Tl in marine matter by direct atomic-absorption procedure using crucible atomizers of solid samples is generalized. To suppress the interferences and to improve the detection limit of the elements in a smaple 5 X 10~(-7)-2 X 10~9-60%, the models of crucible atomizers are presented, proided with dependent heating of the zones of vaporization and atomization-light absorption. The correctness of the method is verified by the analyses of international geochemical standards. The results obtained are applied to the tasks of marine geochemical studies.
