纸离子电泳提供了证据，在稀水溶液中，中性多羟基化合物与碱金属和碱土金属阳离子的络合物的存在。在表1中所述的条件下，使化合物在含有金属乙酸盐的支持电解质中进行精密离子电泳。许多显示出明确的，可重复的运动向阴极，并列出了一些典型的结果。顺式肌醇在所有金属醋酸盐溶液中表现出显著的可测量的移动，并且即使在浓度大大降低时，在Ca u、Sr* 和Ba* 中也迅速迁移;例如，其在0.1、0.05和0.025-M醋酸锶中的相对迁移分别为82、61和45。其他化合物的迁移与金属离子浓度呈近似线性关系。而m-肌醇和m-槲皮醇也表现出相当大的运动
Paper ionophoresis has provided evidence for the existence, in dilute aqueous solution, of complexes of neutral polyhydroxy compounds with cations of the alkali and alkaline earth metals. The compounds were submitted to precision ionophoresis in supporting electrolytes containing metal acetate, under the conditions stated in Table 1. Many showed definite, reproducible movement towards the cathode, and some typical results are tabulated. cis-Inositol was outstanding in showing measurable movement in solutions ofall metal acetates tested, and migrated rapidly in Ca u, Sr* and Ba* even when the concentration was much reduced; eg its relative migrations in 0.1, 0.05 and 0.025-M strontium acetate were 82, 61 and 45, respectively. Movement of the other compounds showed a nearly linear dependance on concentration of metal ion. &And m-inositol and &-quercitol also showed considerable movement
