Spectroscopic Investigations of Soil Humic and Fulvic Acids from Okch'on Basin
Hyun Sang Shin, Hichung Moon*, Han Beom Yang, Sock Sung Yun*
Three humic acids (HA) and one fulvic acid (FA) are extracted from soils of the Okch'on Basin (Koyesan, Yongkwang and Taejon), and are purified and characterized using 1H, 13C NMR, and IR spectroscopic methods. The results are compared with one another and with commerical humic acid (Aldrich Co) and aquatic humic acid from Gorleben underground aquifer in Germany. The IR and 1H and 13C NMR spectral features are found to be nearly identical, suggesting that humic substances formed in the Okch'on Basin have quite similar chemical properties. These humic substances from Okch'on Basin soils have undergone low degree of aromatic condensation and have high contents of aliphatic functionalities including carbohydrates.
