Abstract

The structure of hydrated ions of dichloroacetic acid (DCA) is established by electrospraying aqueous solutions of DCA into the vacuum chamber of a mass spectrograph. At an acid concentration of 0.01 mol/L, the number of hydrated ions decreases monotonically with an increase in the degree of their hydration. The resulting mass spectrum provides information on the distribution of hydrated ions in solution, which makes the mass spectrographic method of spraying electrolytes in a vacuum applicable for determining the composition of electrolyte solutions in environmental studies.

二氯乙酸水合的特殊特征

摘要

通过将DCA水溶液电喷雾到质谱仪的真空室中来建立二氯乙酸(DCA)的水合离子的结构。在0.01 mol / L的酸浓度下,水合离子的数目随其水合度的增加而单调减少。所得质谱图提供了有关溶液中水合离子分布的信息,这使在真空中喷射电解质的质谱方法可用于确定环境研究中的电解质溶液组成。
