摘　　要：电吸附除盐技术(EST)是一种新型的除盐技术,它利用离子和带电粒子吸附在带电电极表面的强化富集得以淡化或净化水,该技术具有能耗小、成本低、不会产生二次污染等优点。通过采用活性炭纤维(ACF)为电极材料来制备活性炭纤维电极对含盐溶液进行除盐研究,考察电压、板间距、板面积对吸附效果的影响。结果表明,电吸附对NaCl盐溶液有较好去除效果,最佳实验参数为:电压1.2 V,板面积100 cm^2,板间距3 mm,最佳去除效率为61.54%。Electricsorption technology(EST)is a new type of desalination technology.It can desalinate or purify water by the enhanced enrichment of ions and charged particles adsorbed on the surface of charged electrodes.This technology has the advantages of low energy consumption,low cost and no secondary pollution.This technology has many advantages,such as good effect,low cost,good control effect,no secondary pollution and so on.In this paper,activated carbon fiber(ACF)was used as electrode material to prepare ACF electrode for desalination of salt solution.The effects of voltage,plate spacing and plate area on adsorption were investigated.The results showed that the best experimental parameters were:voltage 1.2 V,plate area 100 cm^2,plate spacing 3 mm.The best removal efficiency was 61.54%.
