This research determined the optimum concentration of Fe 2+  to degrade waste textile dye by Contact Glow Discharge Electrolysis (CGDE) method with air injection. The addition of Fe 2+  ions can increase the degradation rate of the dye waste due to the radical catalytic conversion of H 2 O 2  producing OH radicals that play a significant role in the degradation process. Remazol Red was used as a dye synthetic dye which was degraded using a batch reactor equipped with continuous cooling water. Experimental results showed that waste concentrations of 100, 200, 300 and 400 ppm obtained the optimum Fe 2+  concentration at 10, 20, 30 and 40 ppm, respectively. The higher concentration of dye waste indicated the higher the Fe 2+  ion requirement to decrease the textile dye waste.
