摘要
对海水腐植质和海洋沉积物腐植质中的碳水化合物组成及含量进行了分析测定,并与陆源腐植质进行了对比实验。结果表明,在海水腐植质和海洋沉积物腐植质的富里酸(FA)和乙醇可溶有机物(ES)的酸水解液中单糖种类和含量多于、高于腐植酸(HA)。总糖含量测定结果与单糖相似。陆源腐植质的碳水化合物含量明显低于海洋来源的腐植质。
This paper deals with the contents of carbohydrates in humic substances (HS) from sea-water and sediments and their comparison with terrestrial humic substances.1. The contents of sugars in hydrolysate of fulvic acids(FA) and ethanol-soluble organic matters(ES) are higher than those in humic acids(HA) from the same samples of seawater or sediments. Sugars are also found to have a greater variety in FA and ES. 2. The contents of total carbohydrates in FA, ES and HA of the samples from seawater or sediments are in a similar pattern as those of the sugars. 3. The contents of carbohydrates from terrestrial humic substances are notably less than those from marine humic substances.
