近年来,研究者们应用穆斯堡尔谱学方法和其他光谱学方法研究了胡敏酸和富里酸中铁结合的物理、化学性质,以及铁的环境和氧化态。我们在经过纯化的胡敏酸中加入丰度为91.8％的~(57)Fe,制备了~(57)Fe-胡敏酸络合物。在不同pH条件下应用穆斯堡尔谱学方法研究了Fe~(3+)、Fe~(2+)与胡敏酸结合的性质。 In recent years, researchers have investigated the physical and chemical properties of iron binding between humic acid and fulvic acid using Mossbauer spectroscopy and other spectroscopic methods, as well as the environmental and oxidative states of iron. We prepared ~ (57) Fe-humic acid complex by adding ~ (57) Fe with 91.8% abundance to the purified humic acid. The properties of Fe ~ (3 +), Fe ~ (2+) and humic acid were studied by Mossbauer spectroscopy at different pHs.
