| Abstract: | In this paper,determination of trace Lead in seawater by graphite furnace atomic absorption spectrometry with APDC-DDTC/CCl_4 system was studied.Under the optimum condition the result of this method was in excellent agreement with that obtained by standard method(R=0.9969).As shown by the test of hypothesis,when the confident level was 95%,there was no significant difference between this method and standard one.The RSD% of this method was 1.1,which was better than that of standard method.In addition,the pro... |
