Investigation on the interaction differences of algogenic dissolved organic matter released by Skeletonema costatum with phenanthrene and 9-hydroxyphenanthrene using spectroscopy

利用光谱法原位研究了中肋骨条藻(<italic>Skeletonema costatum</italic> )在不同生长阶段释放的藻源溶解性有机质(Algogenic dissolved organic matter, ADOM)与菲(Phenanthrene, Phe)及9-羟基菲(9-hydroxyphenanthrene, 9-OHPhe)的相互作用。结果表明,ADOM中类蛋白质组分的比例从延滞期的91%降到衰亡期的77%,类腐殖质组分的比例从9%上升到23%。Phe/9-OHPhe与类腐殖质组分的相互作用更强,其猝灭程度几乎是类蛋白质组分的两倍。此外,短波长类腐殖质和长波长类腐殖质组分与Phe的结合能力大于9-OHPhe,其相互作用参数<italic> Ka</italic>值分别为2.83、3.69和2.39、3.05;而类酪氨酸和类色氨酸组分与9-OHPhe相互作用则强于Phe,其<italic>Ka</italic>值分别为1.87、1.71和1.76、1.38。上述结果有助于深入理解海洋环境中ADOM影响多环芳烃(polycyclic aromatic hydrocarbons, PAHs)与羟基PAHs(hydroxylated polycyclic aromatic hydrocarbons, OH-PAHs)环境行为的异同。
