Colorimetric determination of scandium, yttrium, and lanthanum with ammonium purpurate as a chromogenic reagent

Photometric determinations of scandium, yttrium, and lanthanum with ammonium purpurate as a chromogenic reagent have been reported. The details of the determination of absorption spectra of the chelates, the effect of pH on the absorbance at λ max, the range for adherence to Beer's law, and sen...

Description
Summary:Photometric determinations of scandium, yttrium, and lanthanum with ammonium purpurate as a chromogenic reagent have been reported. The details of the determination of absorption spectra of the chelates, the effect of pH on the absorbance at λ max, the range for adherence to Beer's law, and sensitivity have been worked out.
