| 摘要: |
| 运用差热分析法(DTA)对3种土壤胡敏酸－铜复合物的热分解特征进行了分析。结果表明；络合物与吸附物的热解曲线都有共同相似的热效应峰，DTA曲线的第1,2放热峰可作为区分络合物与吸附物的特征峰。随结合物中配位数（x）及吸附物中含铜量的增加，DTA曲线第1，2放热峰面积及焓变值（△H）均增大。 |

| Abstract: |
| Three kinds of soil humic acid一copper compound substanees were,with
differential thermal analysis(DTA)method,divided into two types of complexes and adsorbed substances.Pyrolytic curves of both showed similar heat effect peaks.The first
and the seeond exothermic peaks of DTA curves were the feature peaks which can be
used to distinguish complexes from adsorbed substanees.The areas and enthalpy change
values(△H)of the both peaks inereased with the inerease of coordination number (x)
of the complexes and copper contents of the adsorbed substanee. |
