The activity coefficient of Er(ClO_4)_3 in DMF was calculated with Debye-Hücker and Osager-Falkenlagen formula, and the effect of temperature and concentration to the mean activity coefficient and the molar conductivity of electrolyte solution have been discussed.
应用电导法在 293~313K温度范围内测定了Er(ClO4 )3 在DMF溶剂中的电导率,利用Debye-Hücker和Osager Falkenhangen公式计算了Er(ClO4 )3 在DMF溶剂中的平均活度系数,并对电解质溶液的摩尔电导率及活度系数随温度和浓度的变化进行了讨论:Er(ClO4 )3 溶液的摩尔电导率值随温度升高而增大,随浓度的变化符合Kohlrausch立方根定律;活度系数随溶液浓度的增加而降低;随温度T的变化规律符合关系式:γ±=A+BT,其线性相关系数R=0。
