硝酸盐是高铁血红蛋白血症的罪魁祸首。长期饮用富含硝酸盐的饮用水可能致癌。电化学反硝化是一种很有吸引力的反硝化技术。虽然在文献中报道了电化学去除硝酸盐，但考虑到与有效去除硝酸盐有关的因素，很少关注新型电极材料的开发。在这项研究中，注意力集中在开发新的电极材料（即阳极和阴极）。在钛基体上镀覆Cu，制备并优化了一种新型阴极.施加电流、电镀时间和Cu 2+浓度是用于优化阴极材料的三个参数。通过在钛基片上涂覆IrO2，开发并优化了阳极。煅烧时间和煅烧温度是不同的，以获得最佳的条件，开发的阳极材料。两种电极都显示出有希望的结果，即使在氯化物中。
AbstractNitrate is a known culprit behind methemoglobinemia. Long-term consumption of drinking water rich in nitrate can be carcinogenic. Electrochemical denitrification is one of the attractive technologies which can be used in denitrification. Although electrochemical nitrate removal is reported in the literature, little attention is paid towards the development of novel electrode materials considering the factors pertaining to efficient nitrate removal. In this research, attention was paid on developing novel electrode materials (i.e. anode and cathode). A novel cathode was prepared and optimized by coating Cu on Ti substrate. Applied current, plating duration, and Cu2+ concentration are the three parameters which were used to optimize the cathode material. Anode was developed and optimized by applying IrO2 on Ti substrate. Calcination time and calcination temperature were varied in order to obtain optimum conditions to develop the anode material. Both electrodes showed promising results even in chlori...
