were coated on a ,titanium, (,Ti,) plate to prepare the SrFexNi1 xO3 /,Ti, electrodes. Afterward, one SrFexNi1 xO3 /,Ti, anode and two stainless steel cathodes were combined to assemble the electrocatalytic reactor (ECR) for cleaning simulated ,nitrogenous wastewater, ((NH4)2SO4 solution, initial total nitrogen (TN) concentration of 150 mg L 1).

Ferrotitanium (,Fe,-,Ti,) is a ferro alloy of ,Ti, and is available in many grades, but the most common grades contain either 10 % to 20 % ,Ti, or 45 % to 75 % ,Ti,. ,Fe,-,Ti, may contain a small amount of C. Since the main use of ,Ti, is as a cleansing agent for S, C, O and N, hence ,Fe,-,Ti, with the lowest possible content of these elements is preferred for steel making. Other impurity elements in ,Fe,-,Ti, can be chromium (Cr), Ni, Zr …
