应用57Fe穆斯堡尔谱学的方法研究了四个不同生长期合浦珠母贝铁的化学状态和Fe2+／Fe3+的值，它们的Fe2+和Fe3+的相对含量分别为4．1％～29．4％和76．6％～95.9％，Fe2+／Fe3+值的变化为0．043～0.42。3个月龄的Fe2+／Fe3+值大于10个月龄，从10个月龄到22个月龄的Fe2+／Fe3+值呈增加的趋势，这可能反映了不同生长期合浦珠母贝对不同价态的铁的需求。
The chemical states and the Fe2 + / Fe3 + values of Fe and Zn + Fe3 + in four different growth stages were studied using 57Fe Mossbauer spectroscopy. The relative contents of Fe2 + and Fe3 + were 4.1% ~ 29.4 % And 76.6% -95.9% respectively, and the change of Fe2 + / Fe3 + was 0.043 ~ 0.42. The Fe2 + / Fe3 + values of 3 months old were more than 10 months old. / Fe3 + showed an increasing trend, which may reflect the different growth stages of Pinus tabulaeformis different prices of iron demand.
