| Abstract: | Absorbance of zinc-iron alloy electroplating solution was analyzed with spectrophotometry, using sulfosalicylic acid as chromogenic agent, ammonium acetate, acetic acid as buffering agent and ammonium persulfate as oxidant. Therefore, iron concentration could be calculated according to Beer's Law. |
