摘 要：本论文讲述了纳滤脱盐和电渗析脱盐的进展和区别，主要是对染料进行电渗析脱盐研究。做了一系列的标准曲线，包括染料浓度与电导率关系曲线、氯化钠盐浓度与电导率关系曲线，染料浓度与吸光度关系曲线。考察染料的浓度、染料中盐的浓度、电流、pH和流量这些因素的变化对染料的脱盐影响。结果显示不同的染料浓度对脱盐的影响不大，不同的含盐量和电流对脱盐的结果也没有什么大的影响。由于染料本身有一定的电阻，所以再高的设定电流也没有实际意义，电流过小会使得脱盐的过程在开始是会有一个恒流过程。pH和流量的变化也只是改变了脱盐的初始速率，并不影响脱盐的最终结果。

Abstract: This article describes the nanofiltration and electrodialysis desalination progress and the difference. Dye electrodialysis desalination research was mainly carried out. A series of standard curves was done, including the dye concentration and conductivity curve, sodium chloride concentration and conductivity curve, dye concentration and absorbancy curve. The effects of dye desalination such as the dye concentration, the different salt concentration in dye, current, pH and flow were studied. The results show that different dye concentrations was the little effect on desalination, different salinity and currents were also little effect on desalination. Because dye has a certain degree of resistance, so to set a high current is no practical significance. If the current is set too small, there will be a constant current process in the beginning of the desalination process. Changes of pH and flow change only the desalination initial rate, affect not the final result of desalination.
