Experiments show that water solution contained 0. 5 -1 % sodium sulfate and 1 - 2% acetic acid is treated by means of electrodialyzer of 200 × 400mm assembled with tri - membrances and 19% sodium sulfate and 20% acetic acid are recovered by concentrating and separating. The content of salt and acid in the purified water is less than 0. 01%, current efficiency greater than 85 %, flow length in 3 ~ 5m and power consumption about 40 ~ 50 kwh/t.

实验表明，含0.5～1％硫酸钠、1～2％乙酸的水溶液通过三对膜组装的200×400mm电渗析器，分别得到含19％硫酸钠、20％乙酸的浓缩液，外排水中盐和酸的含量小于0.01％，电流效率大于85％，流程长度3～5m，耗电量40～50kwh／t。

A new method was proposed to prepare water-soluble ionic liquids by using four-compartment electrodialysis.1-Ethyl-3-methylimidazolium tetrafluoroborate (［EMIm］BF4), used as a model ionic liquid, was synthesized.

On the basis of the preparation of special-grade sodium hypophosphite by one-step method in the high-speed reactor,the produced sodium hypophosphite and the byproduct calcium phosphite were further converted to higher-purity hypophosphorous acid and phosphorous acid products by ionic membrane electrodialysis.

在作者开发的高速反应器一步法制专用级次磷酸钠的基础上进一步将生成的次磷酸钠和副产的亚磷酸氢钙用离子膜电渗析法制成纯度更高的次磷酸及亚磷酸产品，产品质量升级，回收利用了副产亚磷酸氢钙，并减少了原料烧碱的用量。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
