摘要
采用电导法研究了水溶液中盐的浓度与其电导率的关系。结果表明 ,在低浓度范围内电导率与浓度的平方根呈线性关系 ;在较高的浓度范围内 ,首次发现浓度与电导率的关系和 Langmuir吸附等温式中的压力与吸附量之间的关系类似。利用浓度与电导率间的定量关系确定水溶液中盐的浓度 ,比传统的重量法和滴定法快速且准确。
In this paper, the relationship between concentration of salt in aqueous solution and its conductivity has been studied with conductance method. The results show that the function relationship between conductivity and concentration is different within the different range of concentration. Adopting the method of this paper, we could edactly determine the concentration of salt very fast.
