| Abstract: | The difference of maximum absorption between Fe-PCV and Al-PCV complexes was 30 nm. Based on this, a method of dual-wavelength spectrophotometry for simultaneous determination of Al and Fe was establised. The suitable reaction condition and interference were studied. The method was used to determine the amount of Fe and Al in bush feed samples with satisfactory results. |
