ABSTRACT
An online enrichment-separation system of C18 and inductively coupled plasma-mass spectrometry (ICP/MS) with flow injection (C18-FI-ICP/MS) was established for the determination of trace heavy metals in seawater. The optimized experimental parameters including pH,C18 column,concentration of methol in elute and the velocity of elute were investigated. This system was applied to the online preconcentration , separation and determination of trace heave metals in seawater samples successfully. The detection limit (3σ) for Cd, Pb, Co, Ni and Zn was 0.03, 0.09, 0.1, 0.1, 0.3 μg/L respectively. The RSD of Cd, Pb, Co, Ni, and Zn for six measurements of seawater was 6.8%,3.4%,1.3%,2.6%,0.5%,respectively. The accuracy was verified with spiked recovery test. The recovery for five elements was 91.3%,95.1%,100.4%,100.3%,95.2%, respectively.
