Experimental study of microwave assisted of saline water electrolysis

In this article, an up-flow cylindrical electrochemicalreactor has been used to study the microwave assisted ofsaline water desalination. The influence of mainoperating parameters such as current density (۱۰-۵۵mA/cm۲), cell potential (۹-۱۸ v), electrolysis time (۳۰-۱۲۰ s), and electrode diameters (۸-۲۰ mm) and materials(Al and Fe) on the desalination and the energyconsumption of microwave assisted saline waterelectrolysis have been investigated experimentally.Also, these parameters have been optimized correspondto maximum desalination and minimum energyrequirement. The results have shown that Optimumcurrent density, cell potential, and electrolysis timecorrespond to minimum EC and minimum energyrequirement are obtained in the range of ۳۰-۳۵ mA/cm۲,۱۲-۱۴ V, and ۶۰-۸۰ s, respectively. The anode diameterof ۱۶ mm corresponding with the anode to cathodedistance of ۱۵ mm has shown the best results inexperiments.
