本研究首次将XAD-2010和XAD-16聚苯乙烯基树脂用于海水中腐殖物质的分离。比较了不同XAD树脂（XAD-2、XAD-4、XAD-16、XAD-2010和XAD-4+XAD-2、XAD-2010+ XAD-16、XAD-16+XAD-2010）对HS的吸附效率和回收率。通过比较海水样品和不同XAD柱的NaOH流出物的尺寸排阻色谱（SEC）峰面积，评价了吸附HS的回收率。吸附HS的批次回收率在35.2+/-2.4%（XAD-4）和72.5+/-5.2%（XAD-2010）之间变化。XAD-16树脂对海水HS具有最佳吸附性能（柱程序，回收率89.5+/-0.5%），XAD-2010对海水HS具有最佳洗脱性能。制定了海水HS的批量分离程序。(C)1999 Elsevier Science B.

The XAD-2010 and XAD-16 polystyrene based resins have for the first time been used for the isolation of humic substances (HS) from seawater in this study. The adsorption efficiencies and recoveries of HS were compared using batch and column isolation procedures with different XAD resins (XAD-2, -4, -16, -2010 and XAD-4+XAD-2, XAD-2010+ XAD-16, XAD-16+XAD-2010). The recoveries of adsorbed HS were evaluated by the comparison of the size-exclusion chromatogram (SEC) peak areas of the seawater sample and of the NaOH effluents from different XAD columns. The batch recoveries of adsorbed HS varied between 35.2+/-2.4% (XAD-4) and 72.5+/-5.2% (XAD-2010). The XAD-16 resin had the best adsorption properties (column procedure, recovery 89.5+/-0.5%) and XAD-2010 the best elution properties for seawater HS. The batch isolation procedure for seawater HS has been worked out. (C) 1999 Elsevier Science B.V. All rights reserved.
