| 摘 要： | 在293K～313K温度范围内测定了Er(ClO4)3在DMF溶剂中的电导率,根据λ=(K液-K剂)×10-3/c公式求得Er(ClO4)3的摩尔电导率λ值,应用Kohlraush经验规则:λ=λ0(1-βc),使用Origin软件进行线性拟合,作图外推求得Er(ClO4)3在DMF溶剂中的无限稀释摩尔电导率λ0值,讨论了Er(ClO4)3在DMF溶剂中的无限稀释摩尔电导率与温度的关系

| Abstract: | Determined electric conductivity of (Er(ClO_4)_3) in DMF at 293K to 313K. The use of formula (λ=(K_solu.-K_solv.)×10~(-3)/c) has calculated the molar conductivity λ of (Er(ClO_4)_3) in DMF, and using Kohlraush formula (λ=λ_0(1-βc)), The use of Origin Software has made the diagram to push outside and calculated the molar conductivity at infinite clilution λ_0 of Rare Earths salt Er(ClO_4)_3 in DMF obtained by linear fiting, and discussed influence of the molar conductivity at infinite clilution to the Er(ClO_4)_3 electrolyte solution with the temperature. |
