用裂解色谱质谱(PGC-MS)法鉴别了八种不同来源腐植酸(HA)的裂解产物,并根据谱图特征作了分类对比,从两种泥炭腐植酸中分别鉴定出30多种化合物(其中包括质量色谱得到的低沸点化合物、乙烯、丙烯等),其主要组分为一系列芳香化合物及与多糖有关的乙醛、丙酮、和呋喃衍生物以及少量的含氮化合物等。吐鲁番风化煤HA、萍乡风化煤HA和灵石风化煤硝基腐植酸(NHA)裂解产生(除低沸点和高沸点区的裂解产物外)难以分辩的裂解色谱峰,表明它们具有更稳定的结构。而土壤HA、灵石风化煤HA和吉林风化煤NHA介于上述两首之间。
The pyrolysis products of eight different sources of humic acid (HA) were identified by pyrolysis chromatography-mass spectrometry (PGC-MS) and classified according to their spectral characteristics. More than 30 compounds were identified from the two peat humic acids These include low-boiling mass chromatographic compounds, ethylene, propylene, etc.), the main components of a series of aromatic compounds and polysaccharides related acetaldehyde, acetone, and furan derivatives and a small amount of nitrogen-containing compounds. TURQUA Weathering Coal HA, Pingxiang Weathering Coal HA, and Lingong Weathering Coal Nitro-Humic Acid (NHA) cleavage produce (apart from the cleavage products of the low-boiling and high-boiling areas) cleavage chromatographic peaks which show that they have a more stable structure . Soil HA, geochemical weathering coal HA and Jilin weathering coal NHA are between the above two.
