用电渗法去除1,2-丙二醇中的无机盐

摘要

It was studied that the membrane voltage, pH, concentration of original solution on the removal of sodium chloride. The result shows that the membrane voltage of 2 V, pH = 7, after 8 hours of desalination, the conductivity of the solution from 15 000 μS/cm down to 200 μS/cm, desalination rate of 98.7％, can basically meet the industrial production requirements.%用电渗法对1,2-丙二醇氯化钠液提纯.研究膜对电压、pH值、原液浓度等条件对其去除氯化钠的影响.结果表明,膜压为2V,pH=7时,经过8小时的电渗脱盐,溶液的电导率可从15 000 μS/cm降到200 μS/cm,脱盐率达到98.7%,能基本满足工业生产要求.
