| 摘 要： | 采用ＥＳＲ 技术对人工合成混合土和天然高岭土,以及混有Ｃｄ２ ＋ 离子的人工合成混合土和天然高岭土进行了室温、低温条件下的测试分析比较。当土壤中有Ｃｄ２ ＋ 离子存在时,Ｃｄ２＋ 离子进入硅层结构中,使硅层结构缺陷更趋明显,同时土壤中的铁的ＥＳＲ特征也因Ｃｄ２＋ 离子的存在而出现变化,在低温态时有铁的精细ＥＳＲ 特征出现,因此这些ＥＳＲ 特征反映了土壤中Ｃｄ２ ＋ 离子对硅层结构缺陷和铁的ＥＳＲ 特征的影响。

| Abstract: | Analysis and comparisons using ESR at room temperature and low temperatures to examine natural Kaolin, artificial mixed soil with and without containing Cd 2 ion were presented. When Cd 2 ion existed, it entered silica's layers of these soils, causing more obvious defects' behaviours of silica's layer in ESR spectra of these soils. In the meanwhile, the iron's ESR spectra were also changed by Cd 2 ion existing, and hyperfine structure (hfs) of iron could be distinguished in soils' ESR spectra. From these ESR specialities, the influences of Cd 2 ion in soil may be deduced. |
