Thermodynamics Determined on the Dehydration of CuSO4·5H2O
摘要/Abstract
摘要:
通过差热/热重联机(DTA/TGA)测定了CuSO4·5H2O的失水过程,对其脱水过程可能的类型进行了探讨.研究表明,在低温时(100℃以下)CuSO4·5H2O直接脱去气态水,并从热力学理论上分析了脱水过程的原因.
Abstract:
CuSO4· 5H2O has been studied by means of online differential thermal analysis and thermogravimetry( DTA/TGA). The experimental results showed that CuSO4· 5H2O lose water va-por directly with temperature increased. For this case was discussed in terms of thermodynamics.
