Method Comparison of Detecting Ferro in Water Between Fflame AtomicAbsorption and O-phenanthroline Photometry

There are high precision and accuracy to detect ferro in water and wastewater by the method of flame atomic absorption and o-phenanthroline photometry. The concentrations of the samples detected by two methods are 1.37 mg/l and 1.35 mg/l. Both concentrations can reach the standard. In a word, both methods can be used to detect the concentration of ferro in water and wastewater, and we can get accurate results.
