Abstract

Nickel removal from sodium chloride solution has been studied in an electrogenerative cell and the effect of synthesized anion exchange membranes on the galvanic deposition process was investigated. As shown, although in the absence of the membranes, the highest electrical potential of 0.985 volts was achieved, nickel removal efficiency was the lowest. On the other hand, electrical potential as high as 0.976 volts was achieved from the galvanic cell when the UV-curable membrane was employed between the two galvanic cell compartments. Using such electrogenerative process facilitated by the advanced anion exchange membranes, 37.2% of nickel ions were spontaneously removed from a solution of 0.04 M NaCl containing 100 ppm initial nickel ions. Furthermore, the introduced UV-synthesized membranes revealed to have a rigid polymer network and sufficient mechanical and thermal stability with tensile strength of 26.9 MPa and degradation temperature of 415 °C.

摘要

已在电生成电池中研究了从氯化钠溶液中去除镍，并研究了合成阴离子交换膜对电沉积过程的影响。如图所示，尽管在没有膜的情况下，达到了 0.985 伏特的最高电势，但镍去除效率最低。另一方面，当在两个原电池隔室之间使用紫外线固化膜时，原电池可获得高达 0.976 伏的电势。使用先进的阴离子交换膜促进的这种电生成过程，从含有 100 ppm 初始镍离子的 0.04 M NaCl 溶液中自发去除了 37.2% 的镍离子。此外，
