摘要
应用电导法在 2 93K～ 3 1 3K温度范围内测定了Er(NO3) 3在DMF溶剂中的电导率 ,利用Debye -H櫣ｃｋｅｒ和Ｏｓａｇｅｒ-Falkenhangen公式计算了Er(NO3) 3在DMF溶剂中的平均活度系数 。
Electric conductivity of Er(NO 3) 3 in DMF at range of 293K to 313K was determined by using conductivity method. The mean activity coefficient of Er (NO 3) 3 in DMF was calculated with Debye-Hücker and Osager-Falkenlagen formula, and discussed effect on the temperature and the concentration to the activity coefficient of electrolyte solution
