用有机溶剂对冷冻干燥的泥炭样品进行索氏提取和使用有机酸使腐植酸沉淀的两种纯化腐植酸的方法已经被探讨。用有机溶剂萃取，能够有效去除可溶性有机杂质(高达12%)，而对腐植质没有明显损失和改性。使用有机酸为沉淀剂是为了脱除腐植酸中的卤素和无机酸。本文比较了用上述方法获得腐植酸与用传统方法盐酸沉淀获得腐植酸。

Two modiifcations of the standard procedure for the isolation of humic acids(HA) from peat samples have been explored. The modiifcations comprise a Soxhlet-extraction of the freeze-dried peat sample with an organic solvent and the use of organic acids for the precipitation of the HA fraction. The organic extraction effectively removes organo-soluble impurities (up to 12%) without obvious signs of alteration and loss of humic material. The use of organic acids as precipitant aims at the halogen and mineral acid free preparation of HA. Here, the quality of HA obtained using the modoifed procedure is compared to those obtainde by traditional HCl precipitation.
