热滴定方法是建立在传统电解质基础上的分子比测定方法,对添加KgF_2、LiF的电解质,需要 进行修正。本文通过理论分析,推导出添加MgF_2、LiF后热滴定结果的计算公式为:CR=3W(β-1.08LiF％+0.45MgF_2％）-2N/W(β-1.62LiF％+0.67MgF_2％)+N 通过实验样品和实际样品的测定和实际样品计算值与参照值的比较,证明该公式是可行的。
The thermal titration method is based on the traditional electrolyte-based molecular ratio determination method, adding KgF_2, LiF electrolyte, need to be amended. Based on the theoretical analysis, the calculation result of thermal titration after adding MgF_2 and LiF is deduced as follows: CR = 3W (β-1.08LiF% + 0.45MgF_2%) -2N / W (β-1.62LiF% + 0.67MgF_2%) + N Through the experimental sample and the actual sample determination and the actual sample calculated value compared with the reference value to prove that the formula is feasible.
