摘　　要：研究了柱流速和有机物对固相萃取富集水中痕量金属的影响,并比较了两种样品处理方式,发现MAD^(21)SPE的准确度和精确度均超过了传统的螯合-溶剂萃取。The effect of cartridge flow velocity and residue humic acid on the solid-phase extraction(SPE) procedure for enrichment of trace metal elements in drinking water are studied.Compared with the classic liquid-liquid extraction,a better determination result can be obtained after MAD21-SPE.
