| 英文摘要 | An off-line chelation system combined with ICP-MS technique was developed for the quantitative determination of trace elements in seawater,namely V,Co,Ni,Cu,Zn,Mo,Cd,Pb,U and rare earth elements(REEs).The system was built based on an ion chromatography equipped with MetPac~ CC-1 chelation columns which had a strong selective chelation to these target elements within a pH range 5.2—5.6.Acidified seawater samples and NH_4Ac(2 mol/L) were blended to meet suitable pH before being injected into the chelation column,thus target elements were retained while alkali and alkaline metals were excluded.Then chelated elements were eluted by HNO_3(1 mol/L) and samples were collected for ICP-MS analysis.Varying the ratio of input(gen.200 mL) to output(gen.5 mL),the target elements which were concentrated as 40 times as their concentrations were far beyond instrumental quantification limits.At last,a certificated seawater CASS-4 was introduced and our detected values were in good agreement with those certified values. |
