“…Electrocoagulation experimental setup[37] 5 ml samples were taken at2,4,6, 8, 10, 12,14,16,18,20,25,30,35,45,60 minutes in all current densities (48.5 A/m 2 , 97.18 A/m 2 , 194.36 A/m 2 , 291.5 A/m 2 , 388.7 A/m 2 ). After the samples were centrifuged, the measurement of all samples, including calibration, was performed at UV-Vis recording spectrophotometer at intervals of 0.5 nm between 200-800 nm.…”
