摘要

摘要: 河流和海洋沉积物在碱性条件下用温和的氧化剂氧化后,利用气相色谱方法分析氧化产物中的酚类化合物,并与木质素的酚类氧化产物进行比较,以估测沉积物中陆源有机物的影响。比较了硝基苯和氧化铜作为氧化剂的实验结果,并试验了所生成的酚类化合物的毛细管柱气相色谱定量测定方法。九龙江—河口—厦门港沉积物样品中均检测出了木质素,其氧化降解产物具有大致相同的类别组成。说明整个区域都受到九龙江河水输入的影响,该区域沉积物中的木质素主要来源于九龙江河水所携带的陆源有机物。淡水端沉积物中木质素的含量明显高于海水端,表明其分布明显受到河水-海水相互作用的影响。

Abstract: After oxidation of river and marine sediments with mild oxidizing reagents under alkaline conditions, the phenolic compounds in the oxidation products were determined gas chromatographicly and compared with that of lignin oxidation products. The appearance and relative distribution of lignin phenols in sediments were attributed to the influence of terrigenous organic materials. The alkaline CuO oxidation was compared with the alkaline nitrobenzene and the gas chromatographic determination of resulted phenols was tested. The results indicated that CuO is preferable to nitrobenzene as the oxidizing reagent at least for sediment samples and the silylation of resulted phenolic derivatives is essential to gas chromatographic determination with nonpolar capillary column. Clear separation and quantitaive determination of silylated derivatives are realized with only SE-30 capillary column. Sediments from Jiulongjiang River-Estuary-Xiamen Bay have been analized by the settled procedure. Lignin has been found in all the sediments taken from this area with similar oxidation products, suggesting an effect of Jiulongjiang River input on whole the area and that the terrigenous organic matter carried by Jiulongjiang river water is the main source of lignin found in this area. The content of lignin in freshwater- end sediments is higher than that in seawater- end sediments, indicating the effect of freshwater-seawater interaction on the distribution of lignin in this area.
