摘要/Abstract

摘要：

电解质电导率的测定具有操作简单和精确度高等优点,若用于离子淌度的研究将会是准确、简便且廉价的手段。该研究基于电解质电导率提出了新理论方法。以单价离子为研究对象,在不高于0.05 mol/L离子强度下,根据19种单价电解质的电导率数据,将最大偏差接近10%的经验方程修正为最大偏差为5%的精确等式。校正公式的预测值也与移动界面法测定的盐离子淌度和露西方程得到的32种有机离子淌度有很高的一致性。研究还表明19种无机离子与32种有机离子的电解电导率与电泳淌度高度一致。本文还给出了小于0.02 mol/L离子强度下更加准确的方程(最大偏差2%),暗示改进后的经验公式具有极高的精确度。不仅如此,文献中的大量电解质电导率数据均可用于离子淌度的研究,且测定电解质电导率的简便性使得相关研究的深入更加容易。

Abstract:

Detection of electrolytic conductivity can be accurately and simply performed. If such detection can be used for the study of ionic mobility, it may supply an accurate, simple and cheap method for the study. This work develops a novel theoretical method for such a study with electrolytic conductivity. An empirical equation for mono-valent ionic mobility is chosen as the studied target. By adequate data of conductivity of 19 mono-mono-valent electrolytes, we correct the empirical equation with near 10% maximum bias as an accurate one with 5% maximum bias with no more than 0.05 mol/L ionic strength. The predictions with the corrected equation are in good agreement with the exact mobilities of salt ions detected by moving boundary method and in high coincidence with the precise mobilities of the 32 large organic ions obtained by the Lucy's equation. Thus, the work also shows the high agreement among the conductivities and mobilities of the 19 small inorganic and the 32 large organic ions. A more accurate equation with 2% maximum deviation is given under the ionic strength of 0.02 mol/L. The advanced approach holds the special advantages. Firstly, adequate electrolytic conductivities in references can be used for the study of ionic mobility. Secondly, it makes the further study very easy due to the simple detection of the electrolyte conductivity.
